A few years ago: Snowblower, trimmer, whatever won’t start when I need it. Call service shop, haul machine over there and wait three weeks with the other Schmucks in the same position (while no yard work gets done and wife is “unhappy”), not to mention $150 out of pocket. Now: Snowblower, trimmer, whatever won’t won’t start and Dad gets that grin on his face - 30 minutes (or less) later, machine is running, work gets done, wife is happy. I owe it all to Mustie!! My father was a gifted mechanic, but he was killed when I was 8. Always had the aptitude, just didn’t have the knowledge. Mustie has given the knowledge and confidence to tear anything apart and know I have a really good shot at getting it running. There are no words of adequate thanks!!!
Same thing here. Tho my old man wasn't killed, he was otherwise not present. What I did inherit from the man was his penchant for all things technical. I've learned from seeing others do things too. Rumor has it, it was in this same manner my father became a dentist, observing dentists do their thing during WW2 whilst imprisoned in a Japanese death-camp in Indonesia as a young teenager. This, I blame, is the reason I ended up with degrees in mechanical & chemical engineering... and all manner of gadget assembled/disassembled in my man-cave.
I want to thank MUSTIE for the channel and ALL you guys for your comments. Truly a bunch of bright talented people that are willing to share there years of knowledge, THANK YOU ! 🇺🇸
My vote is to adapt one for use as a tiny outboard motor, for something the size of a kayak. The shaft of the trimmer could likely be utilized as well. Keep on keeping on Mustie!
mustie1 is such a terrific teacher. He starts with a basic understanding of how a machine should work, then goes through the steps of verifying function until he finds something that no longer works. This is basic troubleshooting with any DIY project. When we moved from soldered parts/tubes/resistors to circuit boards, we quit repairing the actual fault, but just went to finding the bad module and replacing it. Now people don't even repair cars, they think of them as a module and replace the whole unit.
Wellllll.............it may be so in the US and a few other countries, but from a Third World perspective...........we fix the unfixable ! Nissan or Toyota engines in Kias, Hyundai, Volkswagens, BMWs. Diesel engines in former gasoline vehicles.....you name it. Respect. Trinidad & Tobago.
We have a few saviors of even newer machines in the states. You tube is full of them. As a self described "free loader," fixing and cleaning results in a unit that can be sold and re-used and results in a savings for the consumer, less unnecessary destruction and waste, too.... yeah, I'm justifying my existence, lol.

I’ve had the TB 4 stroke trimmer since 07. Was about twice the price of the cheap two strokes. But dang 14 years and counting! Thanks Mustie1 for another detailed video that I can go back to if needed.
Ahhh the memories, started working on small engines, then graduated to motorcycle and atv. Was a motorcycle tech for 35 years. You do awesome work. Thank you 😊

Several years ago a friend of mine gave me a weed-wacker that had that same model of 4-stroke engine, only it was branded 'Ryobi' and had a centrifugal clutch-drive. I mounted the engine and a car alternator to a little plank and coupled them together and made a portable gas-powered 12 volt car battery charger. I made the coupler out of a socket wrench socket that fit the nut holding the pulley of the alternator and a carriage bolt, and filed the end of the bolt to a square shape so it would fit into the square hole in the clutch socket and passed the bolt through the hole in the wrench-socket and tightened it to the wrench socket with lock-washers and a couple of nuts. The square part of the head of the carriage bolt fit nicely into the square hole of the wrench socket. Thanks for sharing, Mustie1 :-)
Use a square off solid shaft in place of squared off cable and pin it in with a small lock pin. Now you have drive shaft. Idea maybe, worked for me for my kayak.
This was kind of my idea; but instead, drill and tap a hole or 2 in the crank and put a set screw(s) in with lock tight. The problem I see with the lock pin is that it could shear under load. Make the extended shaft long enough that you can put a pulley on it and make a plate and attach it to the housing using the existing screw holes. Put a bearing in the plate to help support the extended shaft.
@@arsler it came as a surprise to me that there is a "pimp my weedwacker" audience, that take weedwacker engines and provide "performance parts" for them. I don't think they're much for using it in the weedwacker per-se, but for using the motor for something else. The venerable homelite weedwacker engines have quite the industry of souped-up parts. Enhanced "big mouth" carb, motor mounts, shaft adapters and many other things. We bought them and turned a homelite into a model airplane engine with a 16" prop (a funny story in and of itself). They're also popular in model boats. The big problem with using these engines for many things is that the optimal RPM is far too high for most applications. Usually around 6000-8000 RPM. There are gearboxes intended for model boats.
I recently bought 4 2-stroke and 2 4-stroke Troy-Bilt weed eaters from a landscaping business for $30 - with help from your previous videos, I was able to get most to run. Kept one of each for the yard and sold 2 others for $45 - also rescued an edger that was considered too far gone for $5 - runs fine now - was about to buy a new one - Thanks Mustie1
I bought one of these used for $50 a couple years ago. It's actually how I wound up finding Mustie's channel, googling how to fix it. So far I've had to replace the carb, replace the fuel lines and filter, repair the weird easy pull start spring, replace the trimmer head and weld the trimmer shaft cable back together twice. I probably spend equal time fixing this thing as I do using it, but I've learned so much from this channel because of it.
I have one just like that. My son in law works for a dump, he brings things like that home and gives them to me to play with. It's been too cold and snowing again to even mess with it. Fun watching you. That would be a good bicycle motor.

Thank you Darren for a VERY interesting class in small engine ! Incredible engineering on such a tiny 4 stroker, and sold so cheap ! See ya next Sunday. Stay healthy, the Ms and you !
I can relate to so many of these videos. While I was growing up, my family lived in a very small town, which had a "dump grounds". The nearest "city" of about 38,000 population, was about thirty miles away. That "dump ground" was more often than not, our local hardware store, lumber yard, appliance repair source, small engine parts supply store, hobby shop and source for any number of other project needs.
Sounds right. We ended up bringing back more than we dropped off at the township dump. They still use the dump but today it's a yard waste dump. I had no idea that dump backed up to the Muskegon River Valley. Meaning any heavy metals or pollution flowed down hill into the river flats. I thought that was dumb until I see the original city dump where I live now also backs up to the boardman River which flows into the Bay. Our forefathers were real idiots!
We have a “transfer station” with a big steel scrap area. Scored some good stuff in there. Sorry, missed the “No scavenging” sign! Went in to dump brush one day and came out almost the same weight. Had the scale person scratching her head for a couple minutes. Faulty scale, was my explanation!
I didn’t visit a department store or mall until my late teens, but we did visit the city dump nearly weekly. Like you, we came home fully loaded coming home every time. Block, lumber, my best toys, bicycles, fans, carpet...if you could think it..it came home. I don’t remember anything quite like this. Just 1000s of blocks...
My dad built most of a cabin out of a couple dumps and stuff picked up off the side of the road. I'm 73 and still cruise around on trash day looking for anything with a motor on it. If it has compression, it's mine.
@@michmvp My Dad was a printer. The paper came in on big pine skids with a pine top - cap. Who ever knew you could build a cabin out of them! Our generation, for the most part, grew up relatively poor and had no problem scavenging and saving. Today? They’d never put down their Starbucks to pick a quarter off the street!
You have to look in places where a lot of Millennials or their rich Parents live . Lower income neighborhoods ,Forget about it ,Their stuff ends up in the Pawn Shop after a couple of uses.
Love your channel, I’m recouping from neck surgery for the next 8 weeks, I’m going to try and watch all your videos. I like your common sense approach to solving the problems of what ever happens to be wrong with whatever you’re working on. You don’t see that anymore, keep up the good work and thanks for sharing your knowledge with the rest of us.
@@irav4u My first thought reading you comment was "why the weld the spark plug to the vise grips?" Then I realized, connect a ground wire with clamp to the vise grips, hold spark plug in vise grips.
The one you’re not working on has an attachment that will let you start it with a drill, very cool the start tool is at Home Depot for about 10 bucks, makes starting really easy.
I just found your channel a few weeks ago I really enjoy it. I can’t stop watching it . Keep doing what you’re doing looks like I have a lot of shows to get caught up on. I loved watching you build crusty.
Pull start: That is the wrist-breaker/shoulder-killer/arm-wrencher "Easy-start" feature from the late 00's. The idea behind the design was to convert distance into torque. Supposedly a granny or a child could start them as the pull start stored the energy of the first 2/3-3/4 of the pull length and then released it during the last 1/3-1/4 of the pull. This was supposed to work better than standard pull-starts where the energy from the pulling of the cord is more directly and linearly applied to moving the crank shaft, basing its function as a starter on the understanding that a well working engine is essentially a coiled predator waiting to leap into action with only a slight nudge by turning the engine through its cycles and applying spark. By adding this Easy-Start, a few things could be changed. First, individuals with less arm strength could start trimmers as there was no longer a need to use momentum (pulling really quickly) or brute force to start a trimmer, the new device took care of both via its store and release design. Secondly, manufactures could warrant further cutbacks in quality in other aspects of the trimmer. If the device no longer needed to be in "ready to start" quality at all time in order for the pull start to actually start the trimmer, they manufactures could lower quality and fall back on the increased torque at the end of the pull cycle to make up the loss in "startability" from reduced quality of build and even later, design. While the physics behind the design was proven (converting distance into torque with a sudden release), the issues with its use in designing these starters, and the source of its nickname, was a combination of cheap build and user habits. The device was never well 'tuned' or smooth in function. The instant when the device converted your long pull with little resistance when pulling, to a pull with high resistance and great force on the engine to start it, occurred with a sudden and jolting change. While not necessarily the intension of the manufacturers or designers, this was the result of the implementation, mnost likely due to restrictions on quality due to cost cutting measures on all but the near-pro level of models. You see, as old Doc Brown would say "they weren't thinking 4th dimensionally!!" While such a pull start may be fine on a new product no one has ever used, putting it on a very well established product meant that 90%+ of users were still pulling on the cords just as they did their previous trimmers; quickly and with a lot of force. This speed and force resulting in the pull start devices being overwhelmed by all the energy being put into them all in a short period of time, the exact opposite of how they were designed to be used; slow and light force. This resulted in the device storing up 2-3 pulls worth of energy and then releasing it all of a sudden near the end of the pull, an amount of energy the engines compression would magnify and shoot back through the system as the engine was not designed to absorb so much energy all in the short time of the pull stroke. I say 2-3 times the energy as keep in mind, the device not only stores the energy of the travel distance of the first 2/3-3/4 of the pull, but also uses energy in the last 1/3-1/4 of the pull. When pulling with decent force and speed you add this this equation inertial energy with does not exist with slow and light force pulls. Thus you end up with the 2-3 "normal" pulls worth of energy which is NOT being used to overcome the inertia of a standing still engine, NOT being used to overcome compression, all because the trimmer was not designed to require such overcoming of inertia, but was designed for the Easy-starts 1/3-1/4 pull distance of sudden stored energy. I would compare it to the difference between a compound bow and a traditional long bow. The compound bow is designed to have the string pulled slow and stead and the bow will let off near end and thus easy the overall pulling of the bow. The long bow has no let off, so often there is a quicker, more forceful pulling action required, with the knowledge the bow will absorb all that force through the entire pull/draw more or less. If you tried to draw/pull the string on a compound bow with the same force and speed as you did a long bow, you will overshoot the pull off point (force required to pull string changes dramatically requiring significantly less force to pull the string further back) and a) hurt yourself, b) damage or destroy the bow, c) Cause a rip in the space-time continuum.) Much are the risks associated with a quick/hard pull on an easy-start of the 00's. Thus you had a well thought out concept, designed in a so-so manner, built crappily, and used improperly by most. Suffice it to say, that feature was not long in the tooth and soon replaced by the modern "Easy-starts" with smoother transsisions in pull force required throughout the pull and those five sided sockets you can use a drill to start your trimmer with. Good day and God bless.
You can mount a plate to the four screws on the front with a bearing and a center pin to the engine. On the other side you can mount whatever you like from a wire, poully sprocket.
Morning Mustie1 (and all the cool peeps that are also watching)! Just starting the vidjayo and want to thank you for uploading. Love your content - makes Sunday mornings awesome !
It's like I'm back in high school shop again, Small Engine Repair and Maintenance. Thanks Mustie1. I have a 2 cycle weed eater that needs gone through again, I serviced it about 10 years ago.
Super Job Mustie1. When I was still doing my own yard maintenance around the house I had a Ryobi that was just like that but the straight shaft (just looked online $149). I bought it at Home Depot in Bakersfield California in 1995 or maybe 96 against the advise of the sales guy. He said I needed the 2 cycle model... Nope, I wanted the 4 stroke... in my opinion that was the right choice. I had that trimmer until I sold my last house in Prince Frederick Maryland in 2017. I left it as part of the home sale along with all my other yard maintenance equipment. I rebuilt the carb on it probably 4 times, changed those gas lines twice and replaced the primer bulb once. The thing still ran great, nice little machine. I never took mine down as far as you just did, thanks for showing me the part of maintenance I never had to do. As usual, great job. Nothing like a Mustie video and a cup of joe on a Sunday morning to keep ya grounded. Thanks!
Definitely, Andrew and Justicescales123... another fun thing would be to attach a small tire to the spinner and use it to propel oneself on skates or a skateboard. lol :-D
Some years ago, I made one MTD trimmer out of three broken, and a little different models) And it worked fine, but looked awful) Thanks for reviving these memories!)
@@Andy-df5fj ya , you have to take 5 minutes to drain that tank and run the engine until it runs out fuel when you store it for winter , even straight gas gunks up the carb eventually
What I’ve found with these small 4 strokes is that if you accidentally touch any of the tuning needles on the carburetor they’re impossible to re-tune. Probably homeowner tried to tune it and made it worse, got frustrated, and thrown it out. I’ve picked at least 10 ryobi 30cc 4-strokes that worked perfectly once I put the carb back to factory settings.
@@averagecarguy420 yep , have had the same experience with these as well , i picked up several at the landfill last summer , all of them had good engines but ran poorly due to tuning or bad diaphragms
Hi there Mustie 1. I live down in Australia and have had a Troy 4 stroke straight shat “Whipper Snipper” as we call them. Mine is branded designed USA and manufactured in Mexico. The Chinese made ones down here are usually clapped out in a couple of years or so. My Troy 4 stroke is 7 plus years now and still starts up and runs strong. Thanks for the rebuild lecture on my old faithful machine. You are a legend!
You have inspired me! Over the weekend I went out and acquired a couple free snowblowers and lawnmowers to tinker with. Love the videos man, cheers from New Hampshire brotha!
Dear Mr Mustie1, I sure do love the will it run, fixing broken motors and stuff videos. LOVE them. But I also yearn for the days of your longer term, dig-in projects like crusty and the cushman. And I’d sure like to see more stuff like that. You’ve started so many great potential projects and then they just vanish. Sometimes forever, sometimes for a year. No criticism at all, I’ll watch and LOVE anything you do. your skills and presentation are literally the best on youtube. I can’t get enough and Sundays can’t come fast enough. But if I could be so bold as to make a request... yours truly, a loyal fan. 😊👍👍
My shop sold a clone of this trimmer years ago. While a 4 stroke is environmentally responsible, the engine transmitted serious vibration to the operator’s hands.
Thank you Mustie1 for dismantling one of your machines for us to see. I appreciate that we can now see exactly how small one of these 4 stroke engines are on the inside. Aint it a cute lil thing lol 😄
Great Job as always, I even learned something new. I have a 2 cycle that is hard starting and I have the little adapter that goes on my drill. Make it easy to start. It is a Troy built as well.
I saw a video years back where someone attached a string trimmer to a trolling motor to make it gas run vs battery. That would be a great use for it one. 😃 I’m glad you did this video cuz I have one like these that I got free & needs fixing. 😊
Excellent video! Very educational and entertaining also! I was betting that engine would not run after you dismantled it and then put it back together again! Glad I was wrong! Thank you so much!👏
14:25-15:15 I see spark on virtually every pull, even before he turned the lights off. Maybe just the camera angle showed it but Darren couldn't see it from his angle?
Couldn’t you hear me yelling, “VALVES Mustie - YOU FORGOT THE VALVES!!” at about 38:20? Also, the portion of a cam that is “off the lobe” is called the base circle. It sounds pretty mean without the muffler!
I caught that too! And I was also telling him to go look up the valve lash spec and break out the feeler gauges, just before he said he wasn't going to bother.
We have a Sthil chainsaw easy start. You only have to pull rope out about 12 inches a couple times to tighten the spring. The guys pull it all the way out. I’ve had to put the rope back in a dozen times cause they try to start it like a regular saw
Dear Paul M. Yes, you are absolutely right. Starting right up, additionally no rodent crap, no rust, no carburator cleaning? Even spark was okay! So maybe it's a fake video? LOL 😂😂 Best regards, luck and health.
Word has got out, if they don't start off comes your carb, and if you still don't start, it's not off to the scrap pile, he is going to fiddle with your cam sharft, crank, pistons and gudgen pins. Cheeky
You should call Aniket from Musket V Twin to make you a crankcase for your proposed 50cc v twin engine. You could call it the Mighty-Mini-Mustie-Musket!
Great videos. I love watching you work on small engines. I've been using the same system you have since I started watching you and it makes working on these small pieces of equipment much easier. Why not take the straight shaft trimmer and turn it into a shallow water boat motor? Put a small propeller on the end and mount it into an orlock on the stern of small boat.
thank you i used some of your video knowledge and got a pawn store weed eater running that my neighbor got for 60 bucks thats only from march of this year . thank you so much!
That would be a joyful-sized motor to tear down with a young lass or lad that was looking in to the mechanical trades. What a fantastic learning device.
I bought a Honda 4 stroke straight shaft type, besides a cutting line bobbin it also has a 3 blade steel cutter for tough jobs. works perfectly many years later.
He's actually teaching us a lesson in "If it aint broke, don't fix it" They both seem to run fine, wsnna take one apart and see how it works?? Who's going to say no. Not here, where's that body hammer at?
Awesome!! You just took apart my engine..engines actually. I have two of them in combi units I use as backups for my lawn care service. I’ve seen some if these come apart before and I think if you go one more level outward you may find a square drive output(can’t remember if male or female). I think the only thing these could be used for is something with a cable drive or maybe some sort of drill device. Awesome job on the tear down.👍👍 That saves me some time if I’m ever curious. Many thanks.
I have/had (it's dead & being tinkered with for another purpose) this same trimmer. The valve-train mechanism threw me for a loop too! Quite the compact design.

While I was growing up, my family lived in a very small town, which had a "dump grounds". The nearest "city" of about 38,000 population, was about thirty miles away. That "dump ground" was more often than not, our local hardware store, lumber yard, appliance repair source, small engine parts supply store, hobby shop and source for any number of other project needs.
Sounds right. We ended up bringing back more than we dropped off at the township dump. They still use the dump but today it's a yard waste dump. I had no idea that dump backed up to the Muskegon River Valley. Meaning any heavy metals or pollution flowed down hill into the river flats. I thought that was dumb until I see the original city dump where I live now also backs up to the boardman River which flows into the Bay. Our forefathers were real idiots!
We have a “transfer station” with a big steel scrap area. Scored some good stuff in there. Sorry, missed the “No scavenging” sign! Went in to dump brush one day and came out almost the same weight. Had the scale person scratching her head for a couple minutes. Faulty scale, was my explanation!
I didn’t visit a department store or mall until my late teens, but we did visit the city dump nearly weekly. Like you, we came home fully loaded coming home every time. Block, lumber, my best toys, bicycles, fans, carpet...if you could think it..it came home. I don’t remember anything quite like this. Just 1000s of blocks...
My dad built most of a cabin out of a couple dumps and stuff picked up off the side of the road. I'm 73 and still cruise around on trash day looking for anything with a motor on it. If it has compression, it's mine.
@@michmvp My Dad was a printer. The paper came in on big pine skids with a pine top - cap. Who ever knew you could build a cabin out of them!
Our generation, for the most part, grew up relatively poor and had no problem scavenging and saving. Today? They’d never put down their Starbucks to pick a quarter off the street!
Jeez, 12 minutes and you already have 112 thumbs up. Somebody has a following!
You are the best teacher. I cannot tell you how much you have helped me learn about these machines. Thank you!
You just saved me a lot of time and trouble. Now I don't need to take one apart just to see what makes the tick. Thank you. Sir!
I have never lived in a place where stuff like this ended up in the dump or on the side of the road. This guy makes a living on throwaways.
You have to look in places where a lot of Millennials or their rich Parents live . Lower income neighborhoods ,Forget about it ,Their stuff ends up in the Pawn Shop after a couple of uses.
LMAO... I like how that shaft sticks out of there. I repeated that when my GF walked by and you said keep your jokes to yourself. Perfect timing.
Love your channel, I’m recouping from neck surgery for the next 8 weeks, I’m going to try and watch all your videos. I like your common sense approach to solving the problems of what ever happens to be wrong with whatever you’re working on. You don’t see that anymore, keep up the good work and thanks for sharing your knowledge with the rest of us.
Just love your narrated videos I just can't tell you everything I've learned from you...can't wait for new videos & anxiously await their posting...
You can use a neodymium magnet to hold the spark plug to ground when checking for spark....save you a lot of hassle. Great video :-)
...not when everything but the plug is aluminum :-)
vise grips with plug welded on- clamp on ground, hook up plug wire
He has done that before. I think he doesn't want to keep track of yet another "thing" for diagnosing.
@@irav4u My first thought reading you comment was "why the weld the spark plug to the vise grips?" Then I realized, connect a ground wire with clamp to the vise grips, hold spark plug in vise grips.
The one you’re not working on has an attachment that will let you start it with a drill, very cool the start tool is at Home Depot for about 10 bucks, makes starting really easy.
Plus, you could adapt that start tool hole as your power take off.
If this was put on a bike maybe make as a push start.
I just found your channel a few weeks ago I really enjoy it. I can’t stop watching it . Keep doing what you’re doing looks like I have a lot of shows to get caught up on. I loved watching you build crusty.
Pull start: That is the wrist-breaker/shoulder-killer/arm-wrencher "Easy-start" feature from the late 00's.
The idea behind the design was to convert distance into torque. Supposedly a granny or a child could start them as the pull start stored the energy of the first 2/3-3/4 of the pull length and then released it during the last 1/3-1/4 of the pull. This was supposed to work better than standard pull-starts where the energy from the pulling of the cord is more directly and linearly applied to moving the crank shaft, basing its function as a starter on the understanding that a well working engine is essentially a coiled predator waiting to leap into action with only a slight nudge by turning the engine through its cycles and applying spark.
By adding this Easy-Start, a few things could be changed. First, individuals with less arm strength could start trimmers as there was no longer a need to use momentum (pulling really quickly) or brute force to start a trimmer, the new device took care of both via its store and release design.
Secondly, manufactures could warrant further cutbacks in quality in other aspects of the trimmer. If the device no longer needed to be in "ready to start" quality at all time in order for the pull start to actually start the trimmer, they manufactures could lower quality and fall back on the increased torque at the end of the pull cycle to make up the loss in "startability" from reduced quality of build and even later, design.
While the physics behind the design was proven (converting distance into torque with a sudden release), the issues with its use in designing these starters, and the source of its nickname, was a combination of cheap build and user habits.
The device was never well 'tuned' or smooth in function. The instant when the device converted your long pull with little resistance when pulling, to a pull with high resistance and great force on the engine to start it, occurred with a sudden and jolting change. While not necessarily the intension of the manufacturers or designers, this was the result of the implementation, mnost likely due to restrictions on quality due to cost cutting measures on all but the near-pro level of models.
You see, as old Doc Brown would say "they weren't thinking 4th dimensionally!!"
While such a pull start may be fine on a new product no one has ever used, putting it on a very well established product meant that 90%+ of users were still pulling on the cords just as they did their previous trimmers; quickly and with a lot of force. This speed and force resulting in the pull start devices being overwhelmed by all the energy being put into them all in a short period of time, the exact opposite of how they were designed to be used; slow and light force. This resulted in the device storing up 2-3 pulls worth of energy and then releasing it all of a sudden near the end of the pull, an amount of energy the engines compression would magnify and shoot back through the system as the engine was not designed to absorb so much energy all in the short time of the pull stroke. I say 2-3 times the energy as keep in mind, the device not only stores the energy of the travel distance of the first 2/3-3/4 of the pull, but also uses energy in the last 1/3-1/4 of the pull. When pulling with decent force and speed you add this this equation inertial energy with does not exist with slow and light force pulls. Thus you end up with the 2-3 "normal" pulls worth of energy which is NOT being used to overcome the inertia of a standing still engine, NOT being used to overcome compression, all because the trimmer was not designed to require such overcoming of inertia, but was designed for the Easy-starts 1/3-1/4 pull distance of sudden stored energy.
I would compare it to the difference between a compound bow and a traditional long bow. The compound bow is designed to have the string pulled slow and stead and the bow will let off near end and thus easy the overall pulling of the bow.
The long bow has no let off, so often there is a quicker, more forceful pulling action required, with the knowledge the bow will absorb all that force through the entire pull/draw more or less.
If you tried to draw/pull the string on a compound bow with the same force and speed as you did a long bow, you will overshoot the pull off point (force required to pull string changes dramatically requiring significantly less force to pull the string further back) and a) hurt yourself, b) damage or destroy the bow, c) Cause a rip in the space-time continuum.)
Much are the risks associated with a quick/hard pull on an easy-start of the 00's.
Thus you had a well thought out concept, designed in a so-so manner, built crappily, and used improperly by most.
Suffice it to say, that feature was not long in the tooth and soon replaced by the modern "Easy-starts" with smoother transsisions in pull force required throughout the pull and those five sided sockets you can use a drill to start your trimmer with.
Good day and God bless.
You can mount a plate to the four screws on the front with a bearing and a center pin to the engine. On the other side you can mount whatever you like from a wire, poully sprocket.
Morning Mustie1 (and all the cool peeps that are also watching)! Just starting the vidjayo and want to thank you for uploading. Love your content - makes Sunday mornings awesome !
KanadianKen - AVe put a new one up yesterday . 👍 🇺🇸
@@libertyman3729 thanks man ! Hope the Dewclaw is involved !! Lol
It's like I'm back in high school shop again, Small Engine Repair and Maintenance. Thanks Mustie1. I have a 2 cycle weed eater that needs gone through again, I serviced it about 10 years ago.
First time I've seen a 4-stroke that the head didn't come off. Love the way you think, I enjoyed the disection.
Thanks Mustie from the other side of the pond
We need a tour of all your projects and what state of progress they're in. I know you have three or four car projects going
Super Job Mustie1. When I was still doing my own yard maintenance around the house I had a Ryobi that was just like that but the straight shaft (just looked online $149). I bought it at Home Depot in Bakersfield California in 1995 or maybe 96 against the advise of the sales guy. He said I needed the 2 cycle model... Nope, I wanted the 4 stroke... in my opinion that was the right choice. I had that trimmer until I sold my last house in Prince Frederick Maryland in 2017. I left it as part of the home sale along with all my other yard maintenance equipment. I rebuilt the carb on it probably 4 times, changed those gas lines twice and replaced the primer bulb once. The thing still ran great, nice little machine. I never took mine down as far as you just did, thanks for showing me the part of maintenance I never had to do. As usual, great job. Nothing like a Mustie video and a cup of joe on a Sunday morning to keep ya grounded. Thanks!
Thanks! Love the Mustie1 format/style. Always feels like I am right there with you.
Sunday night treat for me! I wasn’t tired anyway 😂 best timing ever
They would make a fun project for an outboard on a canoe or something lol
Agree, a little troll motor would be cool.
Definitely, Andrew and Justicescales123... another fun thing would be to attach a small tire to the spinner and use it to propel oneself on skates or a skateboard. lol :-D
I was going to say the same thing. Or maybe even a kayak
Exactly what I was thinking. One of those long poles with a prop at the end popular in the South Pacific.
One person Inflatable pontoon boat.
Some years ago, I made one MTD trimmer out of three broken, and a little different models) And it worked fine, but looked awful) Thanks for reviving these memories!)
Thanks, you have given me the motivation to keep my 30 year old McCullough 282 string trimmer running
You ever thought that your neighbours throw out perfectly good stuff just so they can see it being taken to bits on CZcams.
🤣🤣🤣🤣
Hahaha, NOPE. You're silly.
I have 3 year old Troy Bilt riding mower that was free, the drive belt had twisted and broke, I volunteered to haul it off. Anyone need a good mower?
Then see it running better than it's ever ran
@@dsloop3907 - Yes, but I bet you're not in texas :)
i pick up tons of those four strokes trimmers at the landfill , i think most people prefer the two strokes
Not me. 2 strokes always get gummed up on me. I know it's my fault for leaving fuel in there, but 4 strokes handle my neglect better.
@@Andy-df5fj ya , you have to take 5 minutes to drain that tank and run the engine until it runs out fuel when you store it for winter , even straight gas gunks up the carb eventually
What I’ve found with these small 4 strokes is that if you accidentally touch any of the tuning needles on the carburetor they’re impossible to re-tune. Probably homeowner tried to tune it and made it worse, got frustrated, and thrown it out. I’ve picked at least 10 ryobi 30cc 4-strokes that worked perfectly once I put the carb back to factory settings.
@@averagecarguy420 yep , have had the same experience with these as well , i picked up several at the landfill last summer , all of them had good engines but ran poorly due to tuning or bad diaphragms
I hate 2-strokes. They're so finicky. I think most people have 2-strokes because there are very few 4-strokes sold.
Hi there Mustie 1. I live down in Australia and have had a Troy 4 stroke straight shat “Whipper Snipper” as we call them. Mine is branded designed USA and manufactured in Mexico. The Chinese made ones down here are usually clapped out in a couple of years or so. My Troy 4 stroke is 7 plus years now and still starts up and runs strong.
Thanks for the rebuild lecture on my old faithful machine. You are a legend!
You have inspired me! Over the weekend I went out and acquired a couple free snowblowers and lawnmowers to tinker with. Love the videos man, cheers from New Hampshire brotha!
Best channel there is!
A friend of mine has an engine similar to that in a model boat he built.
Dear Mr Mustie1, I sure do love the will it run, fixing broken motors and stuff videos. LOVE them. But I also yearn for the days of your longer term, dig-in projects like crusty and the cushman. And I’d sure like to see more stuff like that. You’ve started so many great potential projects and then they just vanish. Sometimes forever, sometimes for a year. No criticism at all, I’ll watch and LOVE anything you do. your skills and presentation are literally the best on youtube. I can’t get enough and Sundays can’t come fast enough. But if I could be so bold as to make a request... yours truly, a loyal fan. 😊👍👍
Two fire extinguishers on the same workbench! Now you’re just showing off. Another great video!
Cheers Darren👍hope you're well.
My shop sold a clone of this trimmer years ago. While a 4 stroke is environmentally responsible, the engine transmitted serious vibration to the operator’s hands.
Good morning from CA. Got my coffee and enjoying another great video.
Thank you Mustie1 for dismantling one of your machines for us to see. I appreciate that we can now see exactly how small one of these 4 stroke engines are on the inside. Aint it a cute lil thing lol 😄
Sunday saved by Mustie1! "Kids, daddy is busy now".
No doubt...
What's the story with the orange van? You should update us and your projects, like Jay Leno does. Have a nice day.
Great Job as always, I even learned something new. I have a 2 cycle that is hard starting and I have the little adapter that goes on my drill. Make it easy to start. It is a Troy built as well.
I saw a video years back where someone attached a string trimmer to a trolling motor to make it gas run vs battery. That would be a great use for it one. 😃
I’m glad you did this video cuz I have one like these that I got free & needs fixing. 😊
GREAT video my friend! Loved it...
Hey nice to see you here
What's going on Steve? Having me a Coors light and checking out Mustie1!
It's a 1 Coors light video! LMAOOOOO!
One small engine Hero watchin’ another!
Hi Steve hope all's well got your t shirt and mug
Steve and mustie1 are the kings of small engines 👍
Anyone else notice that Mustie's weed dealer is a junk dealer instead? lol
junkie
@@ppumpkin3282 lol
Hi mustie watching from australia i have learned a lot watching your chanel i think your awsome the way you show us what your doing is awsome thankyou
Excellent video! Very educational and entertaining also! I was betting that engine would not run after you dismantled it and then put it back together again! Glad I was wrong! Thank you so much!👏
14:25-15:15 I see spark on virtually every pull, even before he turned the lights off. Maybe just the camera angle showed it but Darren couldn't see it from his angle?
Me too...
Good morning from south arkansas!
Great Video Mustie love your channel. Wednesdays are when I get caught up in videos.
Great video. I enjoy watching the break down, kinda "how's that work" sorta thing.
I noticed when Mustie gets that first sputter of life out of a dead machine he laughs just like Bob Ross does when he slap cleans his brush.
Couldn’t you hear me yelling, “VALVES Mustie - YOU FORGOT THE VALVES!!” at about 38:20?
Also, the portion of a cam that is “off the lobe” is called the base circle. It sounds pretty mean without the muffler!
I caught that too!
And I was also telling him to go look up the valve lash spec and break out the feeler gauges, just before he said he wasn't going to bother.
Hey, we all make mistakes.
@@Mr.M1STER Take, these broken valves and learn to tune again
Nice, like watching your thought process.👍
Love seeing you diagnose these random motors and engines
Mustie : What you got,?
Musties Supplier: What you need ? I got weed whackers, Lawn mowers , Generators but you gonna pay fat for thoes....😳😳😂😂😂😂😂
fun fact those easy start ones like that often end up breaking from people not knowing better and yanking on them all the time
See it with chainsaw's all the time. If it says easy start do not drop start it. It will break the pull start and will cost $$ to replace.
We have a Sthil chainsaw easy start. You only have to pull rope out about 12 inches a couple times to tighten the spring. The guys pull it all the way out. I’ve had to put the rope back in a dozen times cause they try to start it like a regular saw
Steve’s Small Engine Saloon does a whole show on that subject.
These engines work very well on RC aircraft with a few minor modifications---really sound like the real thing !!!
As always very entertaining very informative I love the way you troubleshoot it is so cool have a good one cheers
On today’s episode, Mustie puts gas in 2 trimmers and they start right up.
Dear Paul M.
Yes, you are absolutely right. Starting right up, additionally no rodent crap, no rust, no carburator cleaning? Even spark was okay! So maybe it's a fake video? LOL 😂😂
Best regards, luck and health.
Word has got out, if they don't start off comes your carb, and if you still don't start, it's not off to the scrap pile, he is going to fiddle with your cam sharft, crank, pistons and gudgen pins. Cheeky
Both had spark, good carbs working parts.. what is this channel coming to? XD
I want to watch you lap those tiny valves for ants 🤣
You should call Aniket from Musket V Twin to make you a crankcase for your proposed 50cc v twin engine. You could call it the Mighty-Mini-Mustie-Musket!
Great videos. I love watching you work on small engines. I've been using the same system you have since I started watching you and it makes working on these small pieces of equipment much easier.
Why not take the straight shaft trimmer and turn it into a shallow water boat motor? Put a small propeller on the end and mount it into an orlock on the stern of small boat.
I was thinking the same thing! 👍
The fuel filter/weight is known as the "Klunk", love your videos.
Yep. Seems like use hobby flyers all know that one.
I was envisioning a motorized skateboard. That motor world be perfect for one.
thank you i used some of your video knowledge and got a pawn store weed eater running that my neighbor got for 60 bucks thats only from march of this year . thank you so much!
I've never seen such cute little motor parts! ♥️
You have the makings of a pair of stern drives for the Beaver!
Who ever worked on it previously wrote Dañado on the fan which means damaged in Spanish
That would be a joyful-sized motor to tear down with a young lass or lad that was looking in to the mechanical trades. What a fantastic learning device.
I bought a Honda 4 stroke straight shaft type, besides a cutting line bobbin it also has a 3 blade steel cutter for tough jobs. works perfectly many years later.
Mustie both plugs are producing spark, glasses on please 🥺
He's actually teaching us a lesson in "If it aint broke, don't fix it" They both seem to run fine, wsnna take one apart and see how it works?? Who's going to say no. Not here, where's that body hammer at?
I love these little engines. They're cuddly and they like to purr.
Awesome!! You just took apart my engine..engines actually. I have two of them in combi units I use as backups for my lawn care service. I’ve seen some if these come apart before and I think if you go one more level outward you may find a square drive output(can’t remember if male or female).
I think the only thing these could be used for is something with a cable drive or maybe some sort of drill device. Awesome job on the tear down.👍👍 That saves me some time if I’m ever curious. Many thanks.
That looks like the perfect engine for a shop class. Pretty dead simple.
Yes but So is a Briggs motor they are more plentiful.
It would be great for shop class, but that went away like 15 years ago....
@@stacycarter8641 which is unfortunate. They don't want people to know how to work anything for themselves.
Good morning America from SE London!!
Good morning from Ottawa Canada
Good morning America from W London
That was great to watch, I fly model aircraft and we have 4 stroke glow engines which go down very small, the pistons on the small ones are tiny
I have/had (it's dead & being tinkered with for another purpose) this same trimmer. The valve-train mechanism threw me for a loop too! Quite the compact design.
