Thanks for watching. This trimmer was running fine until it started leaking some fuel. That was just the start of the problems. In the end I had to adjust the way the trimmer was started but it works every time now. - Auta a dopravní prostředky
Great video, my Ryobi displays the exact symptoms that you demonstrated so well. Thank you
no problem Ash
Great channel. I subscribed because of your clear explanations and the fact that you repair most equipment that is common to your average homeowner.
Thanks. Most shops won't touch the Big Box average trimmers
On my equipment we find we have to adjust the starting procedures as it ages we put a lot of hours on our trimmers and blowers in a year it has just become 2nd nature to use to adjust the starting procedure as they age. Great job as always. Happy New Year!!
Thank you nashguy207 and Happy New Year too.
I agree,I'd be happy with that too. Love the vids, they are so helpful.
thank you Massimo Terenzi for the comment.
When I pull 4 times plus and it doesn't start,then there's usually a few choice words lol, I found out by watching your videos,that when it hits max speed turn it down a ¼ turn and it's perfect, usually I turned it down till the rpms just dropped off and then it seem like it had no power,so I also found out that it drops off at a half turn,so in the middle of that is perfect,thanks for the videos man and helping me figure this out,now my weedeater has great throttle response,it's lasted over a year at this adjustment and still does great
thank you Nate's Outdoors. I appreciate your comment!
Very informative ..Clearly explained and well presented...Well done..
Glad you liked it
Sounds smooth tuned rich for a worn engine. Change the spark plug for easier starting. Good job, buddy.
Yes I think I'll change the plug. Thanks 999thenewman
Great video and thanks for your time.
no problem
Once again you have. fixed some thing that other people would throw out happy new year to you and your family oh by the way I have bought the design can of pb blaster
Happy new you to you as well. I'll have to get a can.
@@HomeGaragechannel thank you
I'm with you and any way it'll start is fine. I usually hood the throttle full open and choke them till they pop and then unchoke them and they usually crank for a cold start. For warm or hot I just leave them on idle with no choke and they usually crank after 1 or 2 pulls. Thanks and Blessings!
thank you Lewie McNeely
@@HomeGaragechannel U2!
Great detailed video and camera work.
Thank you very much!
Happy New Year home garage
Happy new year too
The ones I keep for my own use I just get them to work with the "knack" of knowing how to start them, if they are for sale then I get them to work as they should, or only sell to someone I know, and explain the knack.
Very well said
Awesome video
Thank you Aden Rampersad
Good job.. I find sometimes you have to go back a week later to fine tune once the gasket and diaphragm have set in.. happy new year mate
you are absolutely correct about that Mick.
Wished mine started and ran that well. I would go with what ever worked first and then go from there. Happy New Year to you and your family.
Happy New year too. I appreciate that.
Good video, learned a few things to try on my Shindiawa. Would like to see a Shindiawa 350 Carb. overhaul
thanks, if I can find one, I'll do it.
I did own a few ryobis. It seems to me, that those units are more sensitive and may need adjustments over time. However, I have owned a echo and stihls and never had to make adjustments. Although the carberators have worn out after many years of service.
those are very good points to make.
@@HomeGaragechannel happy new year! Looking forward to your videos in the new year.
@@jimamerica7419 thank you I appreciate it and Happy New year as well
I have a general question regarding 2 cycle oil. I have an edge trimmer that runs on 50:1 gas oil mix ratio. The oil that was provided when I bought the trimmer was a reddish color (as opposed to the dark blue color oil). Can I use the same 50:1 mix but with the blue colored oil instead of the reddish colored oil in the edge trimmer, will it cause any long term or short term damage?
As far as a difference between what came with the trimmer and what you can find on the store shelves I don't think theres a big difference. You can use the blue oil which is what use. The most important part is making sure you're mixing the oil correctly. I don't think anyone would fault you if you tried to find the same oil that came with it though.
I adjust to whatever makes the engine run the best. Did I miss a carb filter in the video? Great job saving that carburetor. Thanks for the video.
Do you mean air filter? Thanks for the comment
@@HomeGaragechannel Yes, air filter
The air filter is the little plastic screen you see there,that's the way they come.
Great video and much appreciated.
Anyone have any idea as to the specific size of the adjustment tool in this video?
There are a wide range of sizes and to be frank I can't see me every needing the set.
I would rather just buy the right one for the job.
I have the manual for mine and it doesn't say in there.
I would recommend on buying the whole kit..
Great video. I've got a very similar Ryobi to the one shown and it starts and idles fine hut when I pull the throttle and then release it, it stalls when instead of returning to idle. Any ideas what the issue could be? Thanks
sure, the carb needs to be serviced or just replaced
Thinking of getting a set of those pac man carb adjusting screwdrivers. I found a set of 8 all different ones for $7 on amazon.
I have a string trimmer by i believe it's craftsman and it isn't running right. It has a warm up feature which locks the throttle at about half open and it runs fine on that but once you press the throttle it disengages that and it tries to run but not very well. Any ideas? I thought it was due to using a gas oil mix of too much oil. Not sure of the ratio but I put in maybe half a bottle of 2 cycle oil per gallon and 4 oz of gas. My gas can holds 1 gallon and 4 ounces of fuel.
I don't want to gum up the carb but I also don't want to blow up my engine.
what's the capacity of your 2 cycle oil bottle? Yes it seems your trimmer runs well on the start position which is part throttle and a lot of choke and when off theres not enough fuel. I would definitely get the tool and turn the screw closer to the filter about a half turn counter clockwise.
@@HomeGaragechannel It's one of the generic small bottles. Not sure of the oz.
Which screw the H screw?
@@coondogtheman is the small black screw closer to the air filter
Is premixed fuel out of the can better or worse than premixing your own fuel from 2-cycle oil and gas out of the pump?
premix from the can is a lot better for small 2 cycle engines.
When I serviced them for Ryobi & did warranty repairs on them some of them didn't start right out of the box & they just needed a carburetor adjustment.
My manager was caught by one which had an air leak underneath the carburetor base from brand new so it had an air leak which is why it refused to start.
In older machines other variables such as a loss of compression is also a cause of hard starting !
Absolutely. Thanks Russell Booth for the comment
Is there a standard adjustment, like turning the screws in all the way and then out one turn or something like that? Thanks
I guess but I don't use it. Try 1.5 turns out from bottom.
@@HomeGaragechannel thanks
@@drivewaygarage1561 no problem
First of all, thanks for this video. Very helpful. I did replace the carb on the same model trimmer and it starts and runs just like it should. But when I shut it down to change the head I have a very hard time starting it again while it is still warmed up. Any tips on starting it while it’s warmed up?
sure, does it matter if you choke it again when it's hot. If so, then the carb could benefit from an adjustment to start better, however the change could affect how it runs. it's a trade off.
@@HomeGaragechannel I have had more luck not choking it while hot. You think my high end is too rich? I’ll try leaning it out a bit. Thanks again!!!
no problem
Now I got a real question for you. Would you ever try your hand in fixing a electric mower or weedwhacker or leaf blower?
I have. All the problems were electrical issues such as switches, or brushes.
Maby can you make a video about it
i know this is unrelated but is there anyway you can link me a keyway for a Husqvarna 322E edger?
You mean for the flywheel?
My Troy-Bilt whacker that I'm trying to get running properly acts just like this one did. Its actually been rather frustrating. I bought a new carburetor and put that on and the darn thing still acts like this even with tuning the carburetor. Just when I seem like I get it right I left up the machine and it will stall. Lay it flat will start and run fine pick it up it stalls yet again.
Did you replace the Fuel Lines and the Fuel filter? sometimes the line will get really soft, and when the trimmer moves, the line will collapse.
@@HomeGaragechannel Nope didn't do any of that yet. It was going to be my next thing of attack. The lines didn't feel soft but who knows about inside the tank.
I didn't know Troy Bilt attachments fit on RYOBI power heads.
most can cross over, it's an issue of shaft diameters and less about the drive shaft. Some of the high end stuff has some proprietary connects though.
Happy New Year, buddy.
I have the exact same strimmer, only difference is my carb only has one eyelet for slotting the throttle cable into were yours has five.
Have you had any problems with the throttle cable going slack and the engine won't rev? The problem seems to be where the cable slots into the throttle lever housing on the shaft, it constantly goes slack from pressing down on the lever. I have taken it apart and it's a flimsy set-up. The cable slots into a recess in the housing but because it's cheap plastic, it won't stay in place. I have to loosen the housing screws, pull the cable back into place and tighten it up again. It doesn't take long before the cable goes loose again. Just wondering if you came across a fix for this?
The only good thing I've found with these Ryobi's is the cardiovascular workout they give you especially when they're hot, they're nearly impossible to start. My strimmer will be the death of me after taking a massive heart-attack.
Thanks in advance for any advice.
Thank you emmams5 for the comment and happy new year to you too. No I haven't had that problem yet and yes it's a flimsy design.
I wouldn’t even pick one of these up for free. Yes, they are in a certain price point but for another $100 you can buy something that will last 10 years or more instead of a season or two. Come on, not even an air filter. That’s a pretty good indicator that it’s garbage and won’t last.
@@andybecker2693 you're absolutely right.
@@HomeGaragechannel Don’t get me wrong. I bought low end cheaper equipment in the beginning because of price and not knowing any better. I quickly learned that that the cheap stuff doesn’t last like the better stuff. Live and learn.
@@andybecker2693 you are absolutely correct. I would think most people started liked that.
Question what are the differences between the Ryobi SS30 and Ryobi CS26 ?
engine sizes
I have Ryobi trimmer about 3years ago. Now, i having problem on my trimmer, when I i put more gas, the motor went shut off or die. Any solution of this problem? Thank you!
easy answer would be to replace the carb and the fuel lines and fuel filter, kits are available for less than $20 USD.
The bullhorn trimmer that I got still give trouble when I'm using it,guess I have to review the video to adjust the screws
It wouldn't hurt. Does it stop working at a certain point or did it stop working?
It still bogging when I throttle it
@@samuelvelez1643 have you looked at the spark arrestor screen?
@@HomeGaragechannel yes I did, in fact I had to put one because the original spark arrestor was missing
@@samuelvelez1643 have you gone thru the carb and looked at the metering diaphragm?
I'd buy parts and get to understand how my machine worked - a new machine is in the hundreds and parts are like peanuts..... by the way at the end sounded great!!
thanks and you are absolutely correct.
When do you decide a unit cannot be repaired because it is not worth the time or money? Low compression?
that's subjective to each case. How much would it be to fix if you did it, How much time would it take , and in the end, would you have a reliable machine for years of use after you're done. For me, if it takes as much money in time and parts as a replacement trimmer, I wouldn't bother.
By the time there is a need to develop a new starting procedure most of the stickers showing the original starting procedure will have faded away/worn out/fallen off, so no problem. 👍😆
you are exactly correct.
On this one I would use it as u fixed it, but still order a replacement carb since they are pretty cheap.
you and me both, thank you skater man.
It is NOT always just because of the caburetter. For my 30cc Ryobi I have had to clean the "spark arrestor" screen at the muffler FIRST. It was almost totally clogged up with soot after a few years and that caused the trimmer to stall.
Hey my friend where did you buy the replacements?
either at amazon or Ereplacementparts dot com
I have the same strimmer can you tell me why the engine turns while I am using it what can I do to stop the engine turning on the shaft thank you
it sounds like the clutch spring is broken so the clutch is alway activated. remove the plastic engine cover and inspect the clutch.
Did you find the solution?
@@SwayNotZay no there is nothing to stop it turning it has not got a thumb screw to lock it in position with out the engine running you can turn it you hold the sponge grip and trigger you can rotate it can’t find any thing to lock it in position Albert
Will any of the H or L adjustments make a 4 stroke strimmers cold start easier
yes
@@HomeGaragechannel which one in particular. I have a new 4 stroke strimmers and i have to pull it 40+ times when cold. Once warm its perfect
that's a tricky question to answer, The L screw is best for "starting" issues
Interesting how it has the pull cord in clutch area. Wonder how that works
Its a very strange setup
Most half crank weedeater's have a starter in that area if you see one at the pull start on the back it means it's a full crank engine which means it has two crank bearings and a better made crank shaft most of the cheaper trimmers have half crank engines but a echo or something equivalent will have a full crank
The starter pulley goes between the clutch and the flywheel, when you pull the the starter it engages with 2 pawls located in the flywheel, this saves space and mony since it's a half-crank desing but it's very annoying when you have any issue related to the starting system with such design since you have the split the machine in two to get to the starter system
Thank you for the information. The trimmer in the video looks like it either shares parts with other models or was originally designed for the 'regular' style starter. Never seen this half crank in Europe, but then again I only work on professional equipment.
@@7eis that makes sense
So getting a new carb will solve the weird starting issue?
possibly not, theres still a chance that you might need to adjust the new carb too. The reason is it could be the wear on your engine that the Carb can't make up for even a new Carb.
I was able to see what was wrong with my trimmer
was it the same problem as this one?
Hi,
Just like the video, the ryoby starts then stops as the engine is flooded. It won't start after that
Please help, I have installed a new carburettor, new spark plug, new fuel lines and filter, I even tried to clean the manifold
When I pull the cord, there is resistance and and it does start for 2 seconds then stops
Only way I get it started na again is that I remove the sparkplug to dry it and then reinstall where it starts and stops and process starts again
I even got a pac man driver and spent hours trying to adjust the new carburettor
unfortunately, it seems the setting they're at, are flooding the engine. Turn the adjusting screws to 1.5 turns from bottom and try starting it again. then makes small adjustment till you get it to idle. You might have to have someone write down the progress of your adjustments, just to make sure the screws don't get out of hand.
@@HomeGaragechannel just to clarify, from bottom meaning clockwise till it stops and then 1.5 revolutions
Thank you for the great video
yes.
Do you have to use pretty cut string with pro head 2
I don't think so
@@HomeGaragechannel pre cut my apologies
I just cut my own string from a small spool of line for that type of head.
@@HomeGaragechannelk cool thanks
Is that the same as a weed eater carb
it depends the weed eater model but I'm sure they make one that uses this carburetor.
Issue spark arrest????
Not this time
These wacky wackers are a pain in the sphincter and its constant and always.
yes they are.
Ethanol in Gasoline (Petrol) destroys rubber parts such as diaphragms in caburetters, fuel lines and o-rings.
Use non-ethanol fuel and add some stabiliser to your gasoline if you do not use trimmer/brushcutters everyday.
It is now possible to buy 40V Cordless or 1200W AC corded trimmers/brushcutters.
your video is nice but you need to adjust the low speed as the same maner you adjust the hi speed found the pick rpm after turn conterclock wise 1/8 to 1/4 ritcher
thank you denis denis
Hey,good day, recently had engine problems, had to buy a new engine,need some useful advice pls,
What happened?
@@HomeGaragechannel went to cut lawn last Friday, after about 45 min,machine cut off and won't start back,so I came back home and got it to start but didn't go back Friday, on Saturday morning I went back and after 25min machine cut off and never start back,Saturday gone I carry it for check an mechanic said piston schored, so end up buying a new engine ,but they also said that stihl oil am using ,that there is a fake oil selling spelt sthil, that's what I was using and didn't know about any fake oil,so basically that's it
what brand of mower is it, and what engine was one there? I guess it sounds like a 2 cycle?
@@HomeGaragechannel it is a cheap machine dunch,but I bought a bigger engine 52cc ,starke brand
This machine last a yr plus before experiencing probs
No spark on the strimmer
how old is this trimmer
probably about 10 years old.
@@HomeGaragechannel Cool
Some say two strokes are easy . New carbs for them .
Very well said
My blower tries to idle higher then normal bur doesn't have enough gas to do it
Might be lean jet or air leak
what's the make and model number of the blower. I'll check to see if I have a video for it.
@@HomeGaragechannel I don't know it's a homelite blower/vac I have a video of it on my channel maybe that will give you an idea of what it is
@@smallengines1018 I'll take a look.
@@7eis good possibility
Where is the air filter?
there wasn't one
@@HomeGaragechannel I would consider putting one on.
The plastic screen is the air filter,they made it that way.
@@jerrysoutherland662 Are you serious?
Yes those are cheap trimmers,they come that way.
Every time he pulls the cord and it doesn't start first or second time, I want to reach through and throw it across the yard. LOL. I hate a piece of equipment that won't start right off.
I understand the feeling.
Corded 120/230V or cordless 40V powered trimmers/brushcutters will switch on immediately.
personally for me i would spend the dough on the good qaulity parts and start it like the original way it,s supposed to be
That's a great point. Thank you Patrick Stapleton for the comment
@@HomeGaragechannel my pleasure mate and Happy New year
@@Patrick4959 happy new years as well
It’s a used Ryobi. Show the new owner how to start it, or they can buy a new unit….I doubt they would read the old directions anyway.
pac man screw driver is just an ignorant way to build this
you're telling me but they really don't us turning these screws.
Those ryobis are junk... If the pull cord breaks on those things, the machine is basically wall art. The procedure to change it requires so much work that you would be under water if ya took it to a small engine shop. If doing it yourself, plan on 3 hours. I would personally stay away from any machine with a pullcord located shaft side. Just an insane engineering gaff.
You are absolutely correct about that. They are a huge pain.
@@HomeGaragechannel My buddy bought the unit that offers all the different add ons. He was 400 deep in extras for the machine when the pull cord broke after only a couple of years. It was cheaper for him to buy a new power head than get the machine repaired. After seeing how extensive the repair was, i wanted no part of it.. Crazy huh?
@@kevinwoodcock7578 wow thats a very good description of what it's like owning one and having it break on you.
Spoken like a true desk jockey, It took me a whole 20 minutes to replace my string and spring! These engines will run just is smooth as an echo, The only problem these machines have is the fact that their owners have no idea what they are doing! I love how everyone in this comment section is thanking him because this video helped them to get theirs started, And then they say that it runs but not real smooth and still having issues starting! I can tell you with 100% confidence that almost everything in this video was incorrect, I can tell he has a little knowledge but not enough to make it run perfectly! First of all there are ports in that carburetor that are most likely clogged! If you’re going to do any type of carburetor repair you should do a complete tear down and then clean and inspect every port in that carburetor, If there is even the tiniest piece of debris in that carburetor he will never be able to tune it properly! You can’t tune a carburetor properly if it is clogged, Even if the carburetor isn’t clogged he’s not going to be able to tune it properly because he does not know what he’s doing! Believe it or not there is actually a certain order you have to follow if you want to get this machine to run perfectly, And I can tell you that going back-and-forth with the adjustments is definitely not the way! People need to stop watching CZcams videos so they can learn how to fix something, The way you left that machine and the statement you made about it running good enough for you tells me a lot about your character! Even though the carburetor was disassembled you couldn’t be bothered to clean and inspect all of the ports, You have the tool to adjust the carburetor but you were too lazy to check Ryobi‘s website for instructions on how to properly tune this carburetor! I hope you are not this lazy with everything that you do, I’m willing to bet that there is at least one woman walking around disappointed! If you do not know what you are doing you should state it in your videos or stop making them! It’s people like you who make these videos and then people try to do it themselves and fail and then go purchase another one! I am an actual Mechanic and I can’t even tell you how many times a person came into my shop because they relied on a video like this and they screwed up their car! These machines will run for many years as long as they are maintained properly, I have this exact machine and it starts with less than five pulls every time hot or cold! You do not need to adjust the starting instructions, Don’t blame the machine because you left the carburetor clogged! I can prove everything that I have said! If someone has one of these Machines and it was running properly and then after sitting for a while it would not start or run properly, You can mail me just the engine and I will make a video of me repairing it and then starting and running just as good as all the others! I can verify who I am and where I live so you don’t think this is a scam, My goal is to teach people that these videos should not be followed! If you want to remove this comment then you should consider removing this video also!
Doesn't matter if it breaks soon
Its a ryobi
No one cares about ryobi lol
its definitely not high quality compared to stihl and echo
Yeah lol
To confusing for a beginner. Ryobi sucks. I am having the same issues. Garbage product.
