Hey man, I just wanted to say thank you. 28" Club Cadet snowblower and stuck with 8" of concrete snow this morning in CO. Hadn't run the machine in a year and couldn't get it to start. To make matters more challenging: I'm a Stage IV cancer patient and don't have the strength I used to. But your "drain the carb" of old gas trick worked like a charm. Thanks for making me feel like a man again. EMW
Early snow this. Now we won't probably get any more snow until February :-)
This video saved me. Followed step by step and it started right up. My man's doing the lord's work over here. 👍🏼
I'm glad I could help!
Thank you! This is the best video I've seen with regards to my snow blower not working. Hard lesson learned. Don't leave the gas in over the summer :(
Glad it helped
This Video saved me!!!! Thank you- After not using my Cub Cadet for two winters I could not get it started.... I followed every step and I am happy to stay it fired up on a single pull Thank you so much!!!! Going to enjoy watching the Snow today falling in Pennsylvania....
Glad it helped!
Thanks so much for this video! Save me from taking it into the repair shop a day before 6-8 inches is set to fall. Worked like a charm!
Glad it helped!
Thank you for this video. Snowblower wouldn’t start today, and I have never taken apart a carburetor in my life. Did everything here and it started right up. Great instructional video!
I’m glad it worked!
A BIG THANK YOU for your help, my main jet was clogged from old gas, it never crossed my mind about the old gas left in the tank, got it cleaned up and running before the snow storm hits tomorrow,THANK YOU AGAIN
I’m glad I could help!
Videos like this save me time and money. My gas had turned to varnish from not treating it from last year, carb jets clogged bad. Figured as much but its nice to have a vid to watch just to give the once over on the removal. Also, on this series of blower motors, just lift the whole darn thing up on end. Auger facing the ground. Easier to access and no gas spillage from fuel line removal on a nearly full tank.
Glad the video helped out. Thank you for $$$
Thank you! Finally got mine going again.
Appreciate it. Glad the video helped.
I followed this and it worked!! Man so awesome I was upset it wasn’t starting this thing is 2 years old! Thanks a lot! Ready for the snow! *Washington state*
Glad you got it running.
Very well done. You explained things very well. Thank You for taking the time to make this video!
Glad it helped!
Thank you so much, mine was this exact issue and now it’s running great!!!
Glad it helped
This video also saved me. Following the steps per video, the snowblower fired right up... even using the pull cord and not just the electric starter. One thing was hard to see in the video and not mentioned was the direction to reinsert the emulsion tube after cleaning. The small end goes in first. Had to watch at .25 speed during disassembly to see how it came out. Thanks again for posting this video.
I am glad the video helped and thanks for pointing out the re-insertion direction.
best video on you tube! it worked exactly as you described thank you!!!!!
Glad it helped!
Followed this video today for our first snow storm and got my snow blower back up and running. I thank God for finding this video. Very helpful even though there were certain parts that the camera wasn't completely on what he was doing all the way. I still managed. I thank God!!
Glad it helped
Thank you so much for the video! Saved our butts before a huge winter storm!
You’re welcome
Small Engine Repair, This was a terrific video. I was having issues with my newly repaired Cub Cadet Snowblower which was fixed in the summer. Needed to clear snow in Montana and couldn't get the engine started. Your video solved my problem. This was excellent. Thank you for taking the time to help. Happy New Year 2025!
I am glad I could help.
Thank you for the break down. It was unbelievably helpful in fixing my snow blower.
Glad it helped
Exactly what I needed to fix my non-starting snow thrower. Thanks.
Welcome
I moved up from Texas to Buffalo, NY to take care of my Dad who had a stroke and is now wheel-chair bound. Bought a Cub Cadet after that crazy blizzard and our plow guy couldn't get to us for days. I put Sta-Bil fuel stabilizer in my fuel tank over the summer (I did a ton of research on how to store these things so I won't get screwed in the winter), and honestly this gunk in the carburetor issue seems to be like it will be the case. First snow of the year and it's been a miserable day. I hate this shit lol, but I love your attitude and I aspire to be as optimistic and level headed as you when it comes to running into problems like this. Thanks again for the video.
You are welcome. I am glad that I don't deal with snow like Buffalo!!
I live in Buffalo actually Lancaster ny/What I do my friend is run it dry at the end of the season in Buffalo that’s late April lol😂. Don’t bother with Stabilizer.
Thank you for this! Really! Followed this taking apart carb, i’m no mechanic, fired right up.
Glad it helped
Can’t thank you enough for this video!!! Back to running like a champ!!
Awesome! Glad I could help.
Thank you! Used this for a Cadet X3. Started up first pull.
I’m glad it helped!
Thank you! Best video I found and was able to get mine going because of this video. Thank you.
Glad it helped!
Thank you for this video. Straight to the point ! Got my unit up and running in about 30 min
You’re welcome!
Thank you so much. This really saved my butt. Mine is maybe 5 years old and looks almost identical to this one. Mine is always a huge pain to start. Once its started it runs like a dream. Always floods or has old gas in the carb idk but I fought with it for almost an hour today. I drained the carb like you did in at the start and if fired up in half a second I was like really thank god. Mind you I already had half the drive way shoveled in pure resentment for the machine. Take pretty good care of my stuff too change oil and sparkplug. Store in a dry place till winter etc. I almost put it on Kijiji I was so upset.
Thank you again. Awesome video
Glad you got it fixed.
I will have to try this out my wont start. I will keep you updated
@@evolawnlandscape sounds good
@ UPDATE!
My snowblower turns on and works like new.
Thanks for this video brother!
I did exactly what you did and it was the carburetor. I didn’t have time to clean it so I just bought one of Amazon for $20 bucks.
If anyone needs the this carburetor for this blower here it is.

Awesome job. You make it look easy!
Thank you! Cheers!
Great video. Thabks for making this.
Glad it was helpful!
Worked like a charm. Thanks!
You're welcome!
Thank you!! This worked great and saved me lots of money!!
Glad it helped!
GREAT video! Sure wish I had a shop with a cool steel worktable like you do!
Someone gave it to me.
Great job, gotta do this, mine is surging, very informative, thanks fornthe help
Glad it helped
Thanks you came through in a pinch
Glad it helped.
Worked great! thx for the video. So is the trick just to run non-ethanol fuel then in the future?
That is best.
This was super helpful, but I think I have to do it again. Seems like it could be the same gas, would you recommend just draining all that’s in there and cleaning, refueling with new gas?
Yes make sure you have fresh gas.
thanks so much. did exactly what you said. worked perfectly.
Glad it helped
Thanks for the how to! I figured as much for mine but I'm sure now
Glad to help
Thank you! I cheated because a new carb on amazon was dirt cheap. These instructions helped make sure I was able to remove the carb and replace it with the new one easy as pie. The only challenge I had by doing a replacement was swapping the extension to reach the choke knob. It's made to go in and stay in so I had to use nippers to cut away the plastic on the old carb that was holding it in place. It would be a lot easier to drain my gas after next winter 🙂
Welcome. I have broke a few choke knobs trying to get them off!
Thanks for this, it got me going this afternoon. The jets were indeed all gunky and I got it all cleaned out, started up as soon as I put it all back together.
However now I cannot open the choke without stalling the engine. I did manage to clear the driveway etc but it threatened to stall a couple of times, i figure what with the choke totally closed the hole time. I took it apart again to see if I'd missed anything, or to maybe adjust that idle screw, but no. Is there anything else to adjust in there?
Nothing else to adjust. Something is still blocking a passage way in the carburetor. You need to clean the carburetor again. Make sure the emulsion tube is clean. Also spray carburetor cleaner through all the passage ways. Make sure to wear safety glasses when spraying carburetor cleaner. If that does not fix it I would just replace the carburetor.
Is there a fuel filter in there somewhere?@@small_engine_repair
If there is one it will be inline with the outlet of the gas tank. @@amhaun01
Newbie here, I took a short cut. I tipped the snow blower to the front where the wheels become propped up. I took the wheel off that's blocking access to the carb. I removed the carb bowl, jet and emulsion tube and cleaned them. Put the parts back on including wheel and it fired up. This was a quicker fix to me being I didn't have to disconnect everything
Glad to hear you got it working!
I'm going to have to give this a try.
I have the exact same snowblower -- 'bout four years old now, and I've always followed the manual to a T. Ran it completely out of gas every spring, stored it dry and empty over the summer, filled with fresh gas a couple of days ago, and suddenly this season it won't start. Got plenty of spark so I'm thinking this is the problem. I'm not quite sure how this is the problem, but I'm guessing just running the 10% ethanol gas through it is enough to do it? Maybe I can find a grade that's ethanol free from now on. What a PITA!
Thanks for the vid!
Let me know how it goes.
do i have to empty the fuel before cleaning the carb? And how do i do that, must i hae a pump?
No. When you pull the fuel line off stick a screwdriver in it.
Thanks. I suspect my CC snowblower has the same problem. Been sitting too long with gas in it and didn't run
It is the most common issue that I work on.
Great video! Quick question I had tho. What size socket do you need to take the spark plug out? I am having issues getting mine out
It should be 13/16. In my tools I have 5/8, 9/16 and 13/16. One of those should work.
hey, thanks for this video - got my cub cadet up and running in 25 mins. Follow-up question, I assume at the end of winter we pop the bowl off and let everything dry out real well after letting the machine run out of gas? Or what procedure do you recommend at the end of winter?
I find it best to drain the gas and then run it until it dies. After that you should not need to remove the bowl. You could just loosen the bolt enough to let the last little bit of gas drain out and then tighten it back up. Also, depending on where you store it for summer, make sure dirt is not able to collect in the carburetor since there is no air filter.
What size screwdriver did you use to remove the main jet? I seem to only have ones that are too big, or barely too small.
With the too small screwdriver I seemed to have scrapped up the jet a bit. Do you think it will need replacement?
I do not know off the top of my head. I will look later today. Some minor scrapping should be ok. Just be careful , it it made out of brass and if you strip it, then you will not be able to get it out.
ive done everything you have done in your video ,new gas new spark plug cleaned out the carb ,and it still wont start,im kind of at a loss ,im most times able to figure these things out, you have any other ideas, only thing is you put that needle vavle in so quick not sure if i put it in right, im taking it apart again for the 3rd time,
The needle valve can really only go in one way. If you spray starting fluid in the carb, does it start?
Does a short extension cord come with the snow blower?
Yes
What size flat 🪛 did you use?
I dont know the size. Just one I had in my toolbox.
good job
Thank you.
What size spark plug socket is needed for this engine? I've tried all of my long sockets and none are big enough and the stupid manual just says "use a spark plug socket"
Should be a 13/16.
@small_engine_repair thanks much; that's 1/16 larger than the biggest deep socket in my set, of course.
Mine won't start with pull but does with Electric start. It pulls fine but just doesnt turn over.
The opening and closing of the intake valve and the timing of the piston creates a suction that draws gas from the carburetor. When using the starter that is happening really fast over and over and it getting gas to the top of the cylinder. Manually pulling is doing the same thing, but not as long as the starter. Make sure that when you press the prime bulb that gas is getting out of the bowl and into the top of the carburetor. That helps when starting with the pull cord.
@@small_engine_repair Thanks for the tip!
Thanks for the video! I’ve swapped the carburetor and the machine is still dying after running for a couple minutes. It wants to run, but kills itself if I put a load in it
Hhmmmmm..... I need some more information to help. What happens when you start it up and just let it idle? Do the rpms go up and down or is it constant? Does it eventually die while idling?
Did this but re assembly oil leaks out of carburetor
Are you sure it is oil? If so, was the engine tipped?
Yes after priming, and pulling to start oil drips from the carburetor, engine wasn’t tipped
tried all of the items as you described and still same surging problem. Removed and cleaned carb twice, drained gas tank, and even replaced spark plug. Same problem. Starts
How did you gaskets/seals look? Damage to them can cause air leaks, causing the surging. I have also cleaned carburetors multiple times and it still surges. I just replace it after that since they are so cheap.
Very quick 😅
Yes
I have to do this every damn year no matter how much I prepare to put the blower away for the season. 😩
Have you tried draining the gas?
@@small_engine_repair I ran fuel stabilizer last year til it was dry. So the tank was empty and I put some ethanol free fuel in and it won’t start. I did buy the fuel last year so maybe that’s bad? Had the same problem last two years and every time I pull the jet out it’s clogged up.
@@_Moto215 Yeah I would not use gas that is a year old. Another thing you could do after you run it dry is remove the side bolt on the carburetor bowl, which is the drain bolt. This way you would no for sure that all the gas is out of the bottom of the bowl.
@@small_engine_repair Will definitely try that. Do you recommend dry tank before storing it for summer or wet with stabilizer? I’ve heard both schools of thought on that.
@@_Moto215 I have the best luck with leaving it dry. Only issue I have seen and had reported is that when adding gas back to the tank, that gas leaks from the carburetor as the seals shrunk a little. Once they re hydrate the leak stops.
They screwed up and never installed a gas shut-off knob. If they had, we wouldn't have this problem
@@Joeteck yeah not sure why they stopped installing them.
@@small_engine_repair I will probably add one myself. Seems pretty simple to do.
Mine is only a few years old and used maybe a dozen times and won't start. Replaced spark plug, put new gas in, and it doesn’t spark
Sounds like you need to replace the coil.
Carburetor needs cleaned out the high-speed jets blocked
Sounds like it.
Ain’t no way in hell I can do this lol
Don’t be intimidated
You just needed to unscrew the two phillips holding down the choke adjustment housing to access the carbon carb to spray ether in and start it up
The two phillips holding down the choke? I am re watching this video and do not see what you are talking about.
Ahh I commented and then a little later in the video I now know what you are talking about. You are correct. However for the initial troubleshooting it is just easier to remove the spark plug and spray some starting fluid in the top of the cylinder than removing all that plastic.
THIS!! Thank you, I never could have taken the carb apart without losing something!
