HOW-TO Install A Snowblower Carburetor

[@konanoobiemaster]

local shop wanted $300+ to replace this exact carburetor!! i ordered one from amazon for $25 and did it myself - thank you very much sir!!

[@michelebroughton6511]

Hello, I am a 76-year-old lady who recently installed a new electric starter on my 8.5 HP Tecumseh Snow King snowblower....I ordered a new starter because my "s...mall engine mechanic" kept replacing the starter with what he had "kicking around"...which didn't solve my problem. My Snow King was purchased in 2004 and has always been stored inside and maintained with regular oil changes and high test gas (and Seafoam additive). Last winter (2021-2022) after having multiple starter replacements, I switched "small engine mechanics" and the new guy told me that I needed to have my carburetor "cleaned" ...he used a carburetor kit and charged me $124.00 for the service....it did not work, and I had to call someone in to clear my driveway. I have been watching your channel...and have ordered and installed a new starter with your help....the starter works great...but still...no start..and gas is leaking out of the carb...so I ordered a new (non-adjustable) carburetor....and I am going to attempt to install it myself :) There is fresh gas in the tank...(Nov 1, 2022)...I am wondering about whether I need to replace the primer and fuel line...and how I would do that with gas in the tank....thank you :)

Perfect video. My 20 yr old craftsman snowblower now runs like a champ. Much appreciated.

[@nickm3558]

I was able to resurrect my old craftsman snowblower '89! Thank you for such detailed videos. You made every step so easy. You take your time to cover every possible challenge that may arise. Great job!! I feel so proud of myself and I saved a ton of money! Cheers

[@deckgun31]

I am not a mechanical person. But I managed to order the correct carburetor, remove the old and install the new in under 2 hours. I'm very pleased with the results. And I couldn't have done it without your video assistance. Your step-by-step tutorials have saved me countless hours and dollars. Plus the confidence boost is immeasurable. Thanks! 👍🏼👍🏼👍🏼

[@jsimm4587]

I actually brought one back to life with a carb half gone inside from the water and methanol only half the threads for the main jet . Ran good for that 15 mins haven’t started it in 5 years but it’s inside not like before set outside I don’t know how long the transmission slide shaft was frozen too . I also have a carb ready to put on it now . Craftsman 28” 8hp .

[@GrampiesWorkshop]

I tried to get parts to rebuild a carb one time and a complete new carb was only about 10 dollars more. Going with the complete carb makes way more sense. Nice repair and thanks for sharing Dony!!!

[@SimpleLife1971]

Today I installed this exact carburetor on my Husqvarna snowblower. The job was pretty straight forward and everything went well. What sort of surprised me was the adjustment which was required to the governor. I've never moved it but once running with the new carburetor, the engine rpm's were much too high. After a couple of tries, in no time the engine was running like new and I was surprised at the dramatic improvement in performance, which brings me to a point 'd like to share. What most of us don't realize is the performance and reliability of our machines degrades gradually over time. Improper maintenance, particularly in the "long term storage" category, allows corrosion to build up over time gradually restricting or outright blocking the small passages in the fuel system. Today's gasoline is not like that of yesteryear. Today's fuel contains all sorts of additives which oxidize mush faster creating all sorts of work for Dony! ALL small engines which will sit unused for months on end should be drained of their fuel completely and the engines run until they stall from a lack of fuel. Like many, I use a fuel stabilizer hoping it works as described. A little knowledge, planning and execution will save a boatload of future issues. Okay, I'm off my soapbox! Thanks Dony!!

[@rhsprecher]

Great video! I had everything done in about an hour! Snowblower runs like new. One tip. The inside nut and bolt is really hard to start when the machine is on its wheels. I stood it up on the auger and could see and manipulate the nut to get it started and tighten it up. This saved me at least $100!

[@jameshaley8162]

....I hope my installation and my snow blower starting afterward goes as well as Yours, Dony. Its December 17th '20...and We have 3" of fresh snow out there and no neighborhood kids looking to make some money shoveling/clearing our driveway. I weep for future generations and this one. Keep up the good work. Thank you for the video.

[@GG-pr3yo]

Just ordered a Toro 826LE carb today (carb, gasket, filter, fuel line, primer bulb) on ebay for $15. You were right, much cheaper than the $150 shop charge + pickup fee. Once I replace it, I'll clean the old one and keep as a spare. Update: new carb went in today, took about 20 min, minor idle adjust. WORKS PERFECTLY. THANK YOU....

[@nolimebdag9883]

Great video, it shows every step clearly and is easy to follow. You even adjust camera angles to show what you're doing which helps so much. Thanks for posting the numbers of the replacements too, that's always another concern when ordering new parts.

Thanks for another amazing video! Going to replace the entire carb on my snowblower. The bowl screw was cross thread. Seems like replacing the entire carb is the best option.

[@bradyedgar]

Thanks!

[@ianmacneil1727]

I was thinking of cleaning and rebuilding my old adjustable carburator but it's cheaper to replace with a new one from Amazon, considering the cleaner, the kit and tools. The thing is I do'nt know what the part number of my old carburator is. My snowblower is a Craftsman 10 hp -30 HMSK100 159212T (D) 3239A with a Tecumseh engine. The numbers on the carburator do'nt match any listed. Can you help me with finding the right carburator? Thank you. Excellent videos BTW.

[@chrisbcritter6112]

I am just starting out, watching a bunch of these videos and doing simple equipment repairs for friends and neighbors. A work friend has a 2014 Bolens (MTD) snow thrower that had a clogged carb - I think it had some of the gas from the very first time he filled the tank still in it, as he hadn't used it much (I worked on it just this Fall, 2018) and never ran it out or stabilized it. I could not believe how much of the machine I had to dismantle just to access the carb! There was a bolt, one of four that held a back cover on, that was blocked by the belt cover. I had to take the snow chute off to get the belt cover off to unscrew this one bolt, to get to where the carburetor was. And then remove a bunch of stuff around the carb! It was a nightmare but I got it done . . . and did not have any leftover pieces or screws. yay.

[@mydaughtersara]

Just ordered a carburetor to fix my snow blower. I am not handy at all, but try videos that can take me step by step through smaller projects. Just want you to know how much I appreciate your detailed and well thought out "how-to"... it is giving me the confidence to give it a shot. You sharing your expertise is greatly appreciated.

[@robertsimonofsky3959]

Thank you for covering the small details…so well explained.

[@tonyizor]

Finally got around to swapping my carb, and your video got me through it no problem! Hats off to you DonyBoy, much appreciated!

[@Jim042744]

Best video I have seen on the carburetor change!

[@timfennell1310]

One tip - the 632334A carburetor kit I got on Amazon had a fuel line. I pulled the old one out and it was difficult to thread the new one through the block. I used an 18" zip tie that I stuck the lock end into the new fuel line and threaded it through the fuel line opening. Later I thought that the easiest way to get the new line in would be to use a dowel (or pencil) to connect the new line to the unconnected old line then pull the old line out. The new one will follow it and be exactly where it should go. The 632334A had 3 adjustments and worked much better than my old non adjustable one. You can even see that the cover has 2 holes in it to adjust the idle stop screw and the low speed idle screw. You can see the holes at 9:23 on in the video. When you look in the holes you see the 2 adjuster screws. So the fixed idle carb was probably a simpler design that saved some money, but the snowblower cover was designed for the adjustable carburetor.

[@JacquelineClayton777]

Thank you! This was just what I needed to watch so I could replace the carburetor on the snowblower. I had a general idea about how to do it but it was really nice to see you doing it and then I knew I could get it done.

[@jflan5954]

Thanks! New carburetor went smooth with help from this video.

[@MattHew-dt3hk]

So helpful and zero fat on the explanation. Thank you so much for this

[@InfamousBMW]

Thank you so so much for posting the part numbers in the descrp. I've been looking everywhere for this carb for my 1979 Aveins RM828 and couldn't find any engine parts anywhere. But that's the exact same carb that it takes. Got the part number from the site you linked and found it for 12$ on amazon. Thanks so much.

[@keithwallin9799]

This video was very. helpful. It matched up with/walked me through everything I needed to do with my carburetor replacement. I especially liked the comments at the end about adjusting the rpm's... I needed to adjust mine down and appreciated the explanation.

[@shawnamison2485]

Great timing on this video, I just replaced the carburetor with an aftermarket on my tecumseh 7hp a few days ago lol. Very easy job. Didn't start right away, it took a bit of playing with the idle screw to get it to fire up, then I just adjusted the high speed adjustment screw and it's running better than ever! I tried to clean the old one, but when I screwed the bowl back in the brass bolt snapped off inside. Whoops. It was probably 20 years old. Slightly different design on the 7hp though. Mine had the plastic choke lever on the top, but its essentially the same steps as shown here.

[@davidr3648]

Great video! I might add that I had to resort to a pair of vice grips to remove the choke mechanism. Those screws were super tight.

[@marathoner43]

Thanks for a great video Don. I did this job today on an old MasterCraft snowblower with an 8HP Tecumseh. The only issue I had was with those bolts for the bracket at about 9:10 in the video. I got the aftermarket carburetor you mentioned in the video, and was surprised to find that there were no threads in the holes for those bolts. Should anyone else have this problem, I used a 9/64" drill bit and an 8-32 tap to cut my own threads and the bracket went on no problem. Thanks again Don. Your videos are always so detailed and so easy to follow, someone like myself with zero mechanical ability can do it.

[@keithanderson6711]

What replacement model did you use? Where did you get it?

[@marathoner43]

@@keithanderson6711 - I used the adjustable model that Don used here (sorry, don't remember the part number), and I bought it from Amazon...probably a small engine dealer who sold on Amazon. I did make 1 mistake here and I wanted to share in case others do. After I changed the carb, it seemed like the engine wasn't revving up as high as it did before. Sure enough, the governor linkage was in the wrong hole. If you use the adjustable model, at 5:53 of the video, Don has a great shot of where the linkage should go.

[@poochie49]

Yeah. Same here. No threads on the bracket holder. No big deal. Did what you did and worked just fine. $16.00 for the carb. Interesting that the carb from a 1974 Tecumseh engine is almost 100% similar to a 2005 carb. I guess the original design was just fine. You know the old saying...if it ain't broke don't fix it". That goes for the carb design also.

[@pepepepert]

My dad suggested your channel as my crafstman 800/24 briggs and straton will start but won't stay running. My first stop will be to replace the carb.

[@rossjanke1386]

Good video. I am using the same new carburetor as you are. My kit came with some brushes with a bit of a bit on the end which I believe is to increase the fixed fuel jet size. My snowblower is hunting a little so I wanted to just barely increase the port size to allow for more fuel. As this video does not touch on this, do you have a video that does? Thanks

I have the same engine on mine, but it's shooting out blue flames when it's running and the idle is surging - installed a amazon carb to get it to start, but now have the blue flames. It's also hard to start.

I am having difficulty with the throttle though. For the throttle lever, there is only a spring that connects to the mechanism that connects to the carb. With the spring alone, it doesn't move the lever open or closed. Is there supposed to be another linkage in addition to the spring? I can see in your video that there is a rigid wire connected to the throttle lever. Im trying to determine if I am missing a piece or not. Sorry for the long-winded question. This is my first time working on this snow blower, so I hope my question makes sense. Any help is appreciated!

For example I have a small Murray machine in right now where the float pin is rusted in the carb, it's not worth messing with where I can just replace the carb.

[@christopherjude]

What would be the spark plug gap for that engine? and what happens if it backfires a small bit

[@rpavlik1]

It's 0.30" on all Tecumseh 4-stroke engines per this "bsi" PDF I have (basically the condensed service guide with just the basics). Should be the way the rj19lm or br2lm (ngk -like them better now) come from the factory, iirc, if that's the plug you use. A little back firing is fairly normal, I think - all the snow king I've ever seen do it. Mine went away when going from 87 to 91 octane, but no-ethanol is more important than a specific octane (they only have 91 without ethanol where I moved to, which is why I switched). Apparently ethanol can cause back firing, as can wrong/dirty plug/gap, too rich of fuel mixture (which might be an adjustment - mixture needles if you have them, or float height - or might be a leak in the float, especially if it's a tec. metal float, pretty common for those to fail and get stuff in them, and consequently not meter fuel correctly) Good luck! You're on the right track watching Dony!
