ALWAYS USE HIGH OCTANE FUEL WITH NO ETHANOL TO PREVENT DAMAGE AND COSTLY CARBURETOR REPAIRS ON YOUR SNOWBLOWER!
donyboy73 I learned that the expensive way! 25 hp Johnson outboard 2 stroke. Bought new in 2005 it was at the 3 years old age but always used fuel stabilizer, winterized it properly in the fall. Because I used regular fuel with ethanol I ended up having to have the carb rebuilt and some other cleaning up of the fuel system. Of course this was after I had tried my back yard mechanic skills on it so it cost me a few more bucks than it would have if I hadnt🤬. So the mechanic explained it this way, it’s not like your car where you drive it daily, with an outboard you get your gas, it sits partly empty, the air temperature gets cool then it gets hot out. Condensation develops and it gets in your gas then messes up your carb and runs like #$&. I replied I use conditioner, he said doesn’t matter the conditioner absorbs the water but it’s still there in the gas tank or in your gas can. Buy shell premium fuel as it has no ethal alcohol in it (Ontario Canada.) The boat is long gone now but ever since only buy the non ethanol fuel for my snow blower and lawn mower now that I know better.
@@TripReviews "... it’s not like your car where you drive it daily,..."
Even in your car, you should NEVER use "regular" gas, if it has up to 10% ethanol in it. That shit just builds up carbon over time on your valves and makes small buildup on injectors, and just generally clogs everything up and makes a mess. Ethanol should be banned for blending in gas (and in some places in the US, it is, thanks to SEMA). They use it pretty much everywhere in Canada. You need to get Super, to have 0% ethanol in it.
Does it look like bird shit inside? I'm looking for a tecumsi carb kit, and 3/4" shaft engine pulley metal, used is fine, what can you do for me?
Good luck finding fuel with no ethanol in most areas of the country.
@@DarkpawTheWolf they sell premium here in Canada with ethanol in it. You have to search for a station that specifically says non ethanol 91. Everything below or above 91 has ethanol too though. So people buy 93 or 94 thinking it’s even better but it’s worse in anything with a carb. I’m starting to think it’s on purpose to screw up everyone’s small engines enough to force people to consider electric small power equipment.
When i see a mechanic taking the time to clean everything and put the rag to not mess up the machine, i click 👍
merci
I agree he is a craftsman
Thanks for sharing your knowledge and skill
Yeah? Is that what you do?
The best small engine repair channel on YT hands down. Great work Don.
My parents gave me a snowblower that had been sitting in their garage for a few years (with old gas still in it), and when I fired it up it was surging and would only run with the choke fully on. I disassembled the carburetor and followed all of your steps and it is now running perfectly (I removed my carb and did the work on my bench). All of the gas in the carb was dark yellow and that little brass screw under the plastic cap was totally clogged. I have a set of micro drill bits but I couldn't free the clog by hand so I had to use my drill press to get through the crud! We have a blizzard coming this weekend and now I'm ready. Thank you very much for your time in making this awesome video!
As I'm speaking for many others as well I appreciate you taking this time out of your day to show us how to do these things
I can't count the number of times your tips and videos have help me out. I've had this surging blower for years and just thought it's just the way it runs. After watching your video. Who knew there was that little screw with the cap. I removed and cleaned it. Engine does not surge anymore. Thank You.
Frankie's Channel @ Kindly donate,thank you!
What is that screw, is that another jet screw like the one on the bottom of the carb?
xXpkMastersXx @ which screw ?
what stage of video,time?
@@jazpanoz4996 11:58 and do most carbs have this?
@@jazpanoz4996 12:00 minutes into the video. I had the same question as xXpkMastersXx.
This tip absolutely works! I picked up an Ariens Pro for a great price since it wasn't starting but it looked new. It was stored with old gas and I knew the jets in the carb were gonna be plugged. Got it to start after a carb clean but with idle surging. Second attempt, I used a micro drill bit on the pilot jet and NO MORE SURGING!
Merci mon donyboy!!!
You're very good at explaining things in a very understandable basic manner. Thank you for taking the time
you've kept me and my old snow blower happy for several years now, thnx don.
As a private carburetor rebuild,or for 30+yrs, I probably would have never thought to share my secrets. I've had to close my doors after covid took everything I worked so hard to get. Glad to see your keeping these machines alive with your experience and knowledge for the DIY back yard mechanic.but if we are giving away secrets..... anyone that owns a chainsaw or weed eater just buy the carb new it's less expensive then the kit to fix it.
It's pretty simple. Keep it clean. Like a good maintained woman.
@@bdyrud80 I prefer my women ...dirty.
The persons who keep everything for themselves aren't the most popular around me.
Passing knowledge is pretty high on my scale of values.
Rest assured, it's not because one has the knowloedge passed to hmi that he has the abilities to perform a repair and there will always have some pople who are just not interested to put their hands inside a motor, a carb, or whatever.
That's what I did.It's a lot cheaper and and quicker
Thanks again, Don. You've taught me so much.
It is nice to see someone who knows and cares about fixing small engines. Very clear and helpful tips for repairing these temperamental engines. You are an excellent teacher. Thank you very much :))
Thank you for this video. We are getting our first winter storm and I was able to help my neighbor with his snow blower that was hunting or surging when running. It is now running normally and it was due to your video that I had the knowledge to try. Thank You for helping the home owner save a few dollars and fix their own equipment!
I have to say in all the years working on machines just changing the spark plug has never fixed any issue.
The jet at 12:15 is the low speed idle jet for those watching that do not know, it is just about always this jet that becomes clogged, or the idle circuit within the the carburetor body itself. Some times they can be an absolute bear. Terrible design that affects just about every tecuntseh motor out there. You have to pass a single strand of copper wire through the idle circuit holes in the carb, and run them through an ultrasonic cleaner most of the time. If that does not work, some times an older machine just needs a bit more gas to idle. Since the low speed idle jet is not adjustable (on the model you show) the idle jet can be drilled out slightly with a micro drill
Great video- I did this thorough carb cleaning once on my old snowblower, however the second time it was coughing and sputtering, I bought a new carb on Amazon for $14.99 and swapped it in about 15 minutes. I found that quicker and more cost effective.
Same with new carb...couldn't believe how well it ran after replacing.
Your videos are the best. Helpful,clear, concise, informative, to the point, balanced and well presented with an even tone. I really appreciate it mate.
I needed you 6 to 10 years ago when my orange blower was surging. I paid for a tune up on it at least twice and they could not stop the surging. So now I know why. I had never heard of a micro drill set until now. I will be ordering one for my hobby work. A great video!
As usual, another great instructional video. Thank you Don!
Thanks for doing another Tecumseh carburetor cleaning ....now in High Definition.
I enjoy watching you work.
how's it going bill?
@@donyboy73 busy busy, you?
@@billlovett4256 yes
My and my brother have a busy week of repairing cars, motorcycles, small engines, welding... As alwais.
Have a good sunday.
A perfect repair method for surging carb, except for one thing.... You must clean the low speed jet and circuit with carb cleaner and straw with the bowl cover off. A lot of dirt will sometimes migrate during the low speed circuit cleaning, into the bowl, re-clogging the main jet. The smaller orifice in the low speed jet is a #78 drill bit.
Good info, thanks.
Dony is one of the best teachers....He explains things very well!
As usual. Very informative and well explained.
Thanks Don👍
You sir are the absolute best there is! Hands down learned everything i needed to know on the carburetor repair.
as usual, an excellent job explaining everything.
I just got a snowblower from a friend with the same problem. Thanks for sharing! Excellent video!
Have a cub cadet blower with same engine & carb setup. Been sitting outside for 2 years. Thanks for the detailed video. Have the carb off & going to go though the cleaning process. As always. Your videos are very detailed & well produced. Thank you!
Awesome videos, really help take the guess work out of small engine repair. Thank you so much
I've heard lawn mowers surging at full throttle and of course the owner just keeps using it like that. Thanks for the video! 👍🇺🇲
Might have been one of the older toro mowers that had an auto full throttle setup, where as soon as it started up it reved itself up until it bounced off the limiter, continuously. Only way to keep it from doing the up down,
up down was to put it under load mowing and then it would stay off the limiter and stop bouncing up down. Very annoying when your mowing short grass and can’t put enough load on the engine to keep it from bouncing off the limiter. They had the same setup on small snowblowers.
I live in Florida, watched this just for fun.
I rarely ever get to watch someone else work. I always lead by example and noted over the years that most people are lazy ass bleeps. I couldn't say how many laborer helpers I have had over my career as an Iron Worker nor now in healthcare but, they are everywhere. What amazes me is that the ones who do as little as possible seem to garner more praise. It is counter productive, literally.
Florida- You are a brat Haha
Texans used to say that too
I feel so much smarter after watching this video. This is my favorite video for 2020. Thank you for so generously sharing your expertise.
Excellent video once again. PERFECTION. I've learned so much from this guy since 2014
thanks for being a loyal viewer
This is a really good video on carburetor cleaning. Thanks for posting this!
Thanks for such a great video. While I lost my rebuild kit before I could get to the repair, I went ahead and cleaned out the bowl nut and the other screw with the tiny orifice and my Yard Machine is running like a champ again!!
Excellent video. Very detailed, in fact the most detailed I've seen yet. Best video I've seen on how to fix a surging engine. Thank you so much, Dony.
you have helped me more than you know over the years ,thanks man from S.W.Iowa
I like using a torch tip cleaning tool. It has different sizes and works well on the different jet sizes.
Excellent video and information. Thank you! I love keeping the older machines running.
Great fix. I don't have a snow blower but as little as they can get used its no wonder why the carbs get muck in them. Excellent camera work as well. Thanks for the video.
I have a 2" and 3" long neck funnels with a attached rubber hose to catch the fuel when taking the bowl nut and bowl off. It then drains into a pan without getting fuel all over everything. Also a Sonic cleaner works wonders.
Love your channel!!
Always amazes me how well these videos are filmed.
With a tripod
@@bigstinkybeans
I was referring to sound quality and lack of annoying background noise but the steady image is not doubt due to a tripod.
Excellent! Video, sound are very clear and focused. Don, the mechanic explains each step clearly making it very understandable.
Great job! One of the best tutorials!
Joe
Thanks a lot for putting this video together. I'm going to fix my parents old snowblower thanks to you.
Another quick tip is to use old guitar strings to clean out the jets if you don’t have small drill bits Thanks for the vids love your work. From Ottawa
I use a B string to clean the idle jets on my 1970 Norton 750 Commando. The jets are 0.016 inches in diameter and the B string is 0.015 inches. Go figure that out.
I don't play guitar, but eat plenty of bread. I strip the paper off the bread tie, and the exposed wire is perfect.
Don:
This looks like an encore presentation.
I use a piece of wire from a steel brush to clean the holes. A trick I learned from you many years ago that works well and it is less time consuming.
You look younger on this one too.
Guess you can watch your self age just by going back over your vids.🙃
Another storm here today in Gander
60 cm on the come.
I used an e string from my guitar.
I used my Toro snow thrower with a tecumseh engine just yesterday and am going to apply what you showed me here to fix the surging that is happening on mine. I am hearing some popping going on so I might have some other repairs to do but I hope not. Thanks for another great video !
Hey donyboy you just saved me a service fee! My snowblower has been surging for a few months and I kept procrastinating on sending in to be fixed because this machine is super old...over 30 years. All it needed was to adjust the governor.. took all of ten minutes to get in there and move the spring a bit. Thank you so much!
Thanks for your video. I’ve saved it for future reference. Your demo happens to be with my exact snowblower.
A million thanks for your video. I have learned a lot from all your videos but this one save my day. The hiding screw behind the plastic cap did the trick for me. Amazing.
Thank you for another expertly produced guide with great presentation and video production. And not to forget how useful and handy these tips are. I watch your videos even if I don't have any current issues with my engines, just good learning for when I need it.
It’s mechanics like this that you can learn a whole lot from. You can tell from the detail that he gives here that he has a lot of experience, and I could watch him work all day!
Really liked the tip of standing the blower up on it's blower housing.
Now doing that, it doesn’t send oil back through the engine. I did that one year and I had a hell of a time getting it to run. Just wondering.
@@jamesbarlowjr.3762 Is it possible the fuel tank was sort of full and flowed through the carb into the cylinder due to gravity? (just guessing)
@@NoferTrunions Hello, actually now that I think about it, it was my mower. Would that make a difference? It almost seemed like it was hydro locked. And ran really shitty. And the more I pulled on the string and it retracted it definitely got looser and eventually started, blue lots of smoke then cleared up. Sorry maybe it wasn’t the blower. My bad.
@@jamesbarlowjr.3762 The "lots of blue smoke" and "won't start/run" are common symptoms of a leaky needle and seat in the carb. The carb slowly leaks gasoline into the cylinder, it leaks past the rings and gets into the oil. Check your oil level - is it above the FULL Line? Does the fuel smell like gasoline? I had a rototiller that did that. Never thought it could have been a leaky carb.
@@NoferTrunions well after I got it to run, and it cleaned itself out, it seemed to be fine. It was put away for the winter
Your channel is so helpful. I got machines and chainsaw problems fixed with your help.
Wonderful video and so much help. I have a Toro 826LE and had it serviced completely two years ago when the electric starter failed. Did not have the occasion to use it last year and this year when I started it up it was surging. Even though I run treated ethanol free gas I had not run the gas out for storage, my bad. After watching your video i cleaned the jets and put in fresh treated ethanol free gas and thats all she needed. Running fine now. Saved me a ton in tune up, pickup, and delivery charges. Thank you for sharing your knowledge.
It's a pretty good repair, but I would advise taking the carburator off to make it way easier and do a better cleaning, unless you don't want to risk changing a gasket. Also cleaning the low-speed jet is pretty important
If I may add, I find that ‘electrical contact cleaner’ does a great job of removing accumulated particulate and ensures excellent power contact.
Your videos are great! As a lady operator, I appreciate all the information I can glean from the experts. Bless you!
thanks again for this, i got my snowblower going this morning by following your vireo. the float bowl had some crap in it and i cleaned the jets and float valve. works great now!
An excellent tutorial video as always :-D
I had a similar effect years ago on my old B&S lawn mower, the layered pumping diaphragm was had it.
One of your older videos pointed me straight to the fault, about 10 years back.
Much respect from everyone here at Vikingbags!
Another quick tip is to tilt the machine so that any dirt and water go to the lowest point in the fuel tank, then use a small hose to siphon out the dirt and water. Use a flashlight to light up the inside of the fuel tank so that you can see exactly where the dirt and water are at the bottom. Do the same to your gas cans and gas containers.
Just followed the process in this video to fix my snowblower's carburetor today! Great video!
This is exactly what I needed. Thank you for demonstrating this.
Rimming the jets out is a must .. it just gives a bit more fuel.. good fix..
I REEM them out I hate when people rimm them out . It hurts too much !
Another GREAT video!!! Thank you!
I use ethanol-free gas with my Ariens snowblower and after every use, I drain the gas from the carburetor bowl via the drain bolt on the bowl.
The new carburetor bowl you installed(which did not come with the kit) did not have the extra drain bolt used for draining fuel from the bowl.
1) Why didn't you reinstall the old bowl?
I would think being able to easily drain the gas from the bowl an easy and important step to help keep the machine from having fuel issues.
2) Am I correct?
That machine did not have a fuel shut off valve but vise grips could be used to pinch the fuel line so one could drain the bowl. (or one could install a shut off valve)
From what I saw, the problem of the surging might have been solved by just cleaning the jets without a carb rebuild. For the average Joe like me, I would have cleaned the 2 jets before doing a rebuild.
3) Is that a common sense thing to do?
Great job on the video! Your step by step guides are very easy to follow.
Perfect instruction . I own a 23 year old Craftsman with an 11 HP Tecumseh . I replaced the friction wheel and both belts but your video cleared up the surge. I am on the 3rd carb on that machine but as long as it does the job i see no need to replace it. Thank you for taking the time to showcase these fixes. Cheers
I always install a fuel shut off . So I can tell the costumer to run the carb. dry between runs , so you do not have gas going bad in the carb .
same here, sometimes they are too cheap to pay for the shut-off valve lol
@@donyboy73 Which is crazy because they are not expensive at all! Although my new Craftman has a Honda style carb and the fuel line is not easy to get at to put one on. And the cover for the carb is harder to remove because of the primer line.
I have a 1990s Ariens with similar engine. It has a fuel shutoff. But after shutting it and running 'dry,' there is still a bit of gasoline in the bottom of the carb. My Tecumseh carb has a "dump valve" and I always get a few CCs of gas out after the engine runs dry. I always drain the dump valve when emptying the carb. During summer, I empty everything included the tank, lines, etc.
Does letting it sit with no gas cause the seals/gaskets to dry up over time though?
I say the same thing to my customers.
Very well produced video, only would add a few suggestions. Should clean area around the idle jet before removing to prevent debris from entering, plus spray cleaner through the idle jet passage while it's removed. While the bowls off it's a good idea remove the main and pilot jets for cleaning if equipped. Also, Honda carbs main tube has many tiny holes through the length that get restricted. I'm probably too meticulous to make money doing small engine repairs as I tend to leave no stone unturned.
👍
Rollo Tomassi, you're the one who gets away with it
Super helpful Dony. I watched a couple of your videos to get a used snow blower going again. Thank you very much.
A very handy video for me. I have saved it and subscribed. I have a Craftsman's nine horse snowblower. Had the same surging problem. Just before this winter season, 22 - 23, I have machine into a mechanic for that issue. $300 later I ran across your video.
As I write this I hear my neighbor's snowblower running and surging. I'll send him this video and maybe this summer he and I will work on his snowblower.
My MTD w/8HP tec runs ok until you put a load on it and then it stalls and quits. Any ideas? What make/brand of digital RPM reader do you recommend. What is the best way to adjust RPM?
Thanks for another great video. I've learned a ton from your videos. My small engine equipment is all I have left to tinker with. We bought an electric car, so no tinkering with that.
Excellent video! This video and the one you made about carburetor adjustments has helped me immensely! Thank you for taking the time to show us how it's done right.
Great to hear!
Great work Don! Its always satisfying when a diyer gets the job done using your expertise. God bless!
Nice job. I miss the old school float bowls with the spring loaded drain valve built in. Only very rarely did you need to pull the bowl, since you could drain a little before each use and crap never had a chance to build up in there.
Sshhh! They'll hear u!
I buy spare carbs, but only if it has the built-in drain. I hit it each time I run it at the end to drain water, hopefully. I also put stabilizer in my gas cans before filling to prevent problems.
Also keep Seafoam on hand for once a year treatment.
Seems to be working !👍
Not much storage so some of my machines live under a tarp.
I spray them down from time to time with whatever lubricant is handy to resist corrosion... hope to have a roof some day!🤣😂
Good thorough repair. 👍
Great video! Followed every step + a spark plug change. Everything is up and running ! Thanks 👌🏽
Hello Don. I just wanted to thank you for posting this great video. As it turns out I have the exact machine which was running on choke only. The bowl nut was plugged solid and so was the Air mixture screw. Working like new again. Subbed
🤪When I retire I’m moving to Florida to open a snowblower repair shop. 😃
lol
I've found a lot of times surging only requires cleaning small idle hole at edge of threads in the bowl nut.
Can you explain quickly how to do that please?
Very good video! You didn’t rush through it & took your time to show us how to repair it. New subscriber now. Great job! 👍🏻
You do a great job explaining how and what you are doing. Great job!
Wow, the detail n time you took in this video was great! I'm a Truck and Trailer mechanic myself but Im shy around small engines, I look forward to watching more of your videos, like I'm realy blown away with the care and detail in this video. Keep up the great work!
( I also wonder if that's a Quebec or Acadian accent, i'm on the east coast myself?)
northern Ontario french accent
Agree. Well said!
Great video! Quick question - I see the rebuild kits on amazon for $10 and a whole new carburetor is $15. Would it make sense to just buy a new carb instead of rebuild? Would that be easier?
Yes, it is much easier and cheaper to buy and install a $15 carburetor.
Thank you Don, for making & posting this video.
I just did the same repair on my own Craftsman snowblower, which is 40 years old by the way! It has fully adjustable low and high speed jets on the carb, so it has a few more parts and so a little more work was needed to get the job done.
Lots of rust on the levers around the carb. I bet it’s stored outside.
I had a lawn mower that surged. I followed this procedure, and I found that there was mud and water in the carburetor bowl. I don't know how the mud entered the carburetor, but draining the fuel from tank, rinsing the inside of fuel tank, and spraying the carburetor with carb' cleaner solved the problem.
The mud would be the gasoline turning to varnish.
Best clinic there is,thank you,neighbor to the north!
Thank you so much for showing me this, i have the exact same snowblower and now im going to fix the surging problem tomorrow thank to you!
"A lot of Tecumseh engines do not like to idle" Ain't that the truth!
There are two tiny passages in the throat of a Tecumseh carb that are for the idle circuit. Very often these passages will become clogged with varnish (residue of dried fuel). I clean them with a piece of bare copper telephone wire. It's easier to do if you remove the carb first.
@@josepha8759 Exactly, it´s not the fault of the engine manufacturer or the carb, but of the incompetent user or mechanic who isn´t capable enough to clean a carb or drain the fuel when the unit is not in use.
@@v-g-z3689no... it's the fault of whoever required ethanol to be added to gas.
@@Tbizzh That is also true.
Tecumseh's are that way when new
No one is meticulous as Donny Boy, my area are filled with butchers!
Ive got the same one that was giving me the same problem. I missed the second small hole on the bowl nut. Thanks for the help.
How's she goin'? That's a great way to clean the carb while it's on the machine. A fuel shut off is nice to have, so I try and install one on my machines. Using the K100 is a nice touch as well. Shows you care about the machine and customer. Thanks for posting and take care!!
All that fuel spilling with wood stove burning 🔥
Yes good way to blow up garage.
Vid on a choke spring PLEASE?(tecumseh) Mine no longer holds the choke in its positions. I cannot find a vid for this.
ok
My surging blower cub cadet was driving me crazy, thank you so much for your precise easy repair, appreciated.
Awesome video Don. Many blessings to you and your family.
so, the surging could have been fixed by clearing the jets in the second part?. the carb kit was not really the fix, just nice to do while you had it
I agree the needle valve holes when clogged cause surging.
@@joec2174 wgich 2 jets ? the bowl jet and the side jet?
@@featherlite7873 bowl jet Most common issue.
I know the customer asked for a rebuild kit, would have interesting to see if the surge would have been cured by adding K100 and cleaning the side jet?
Not likely.
My experience with single cylinder engines with similar carbs, the surging is caused by a clogged primary/idle jet (the second one that Dan cleaned). This jet need to pass fuel all of the time, even at full throttle. If not, the engine runs too lean, stumbles and then the governor catches it before it dies completely and over revs the the engine. The secondary/high speed jet (bowl nut) and/or the emulsion tube are rarely the culprit.
The real problem is, for many years, the primary/idle jet has not NOT accessible. The only way to clean it is to disassemble the carburetor and soak it in a bucket of cleaner or better yet an ultrasonic cleaner.
I've cleaned many a carbs, it's amazing what just a little debris will cause. I always tear down and clean out like Donnie did in the video. Just would have been interesting to see if that might have worked is all. Thanks for the reply Jack👍
Great video👏 Just what I needed to know.
I will add that I had an old lawyer mower that was surging. The carb had simply vibrated loose. Like that easy fix.!
Thank you for making some of the best small engine videos on CZcams! I had to subscribe, you are a great teacher.
