Snowblower not starting

Hey guys!
I have an older Craftsman 22in single stage snow thrower. Just had it tuned up and the carb repaired. It's ran great the past 3 times I've used it, but today I went through some deep snow and it backfired (pop with some black smoke out the exhaust) then died. I restarted it and it died almost immediately, and I cant get it to start again. Any advice to get it up and running? I did put some gas in it earlier today that's probably 6mo old, could that have played into it?

I don't know a lot about small engines but am pretty handy.
Thanks!
Thanks

Try fresh fuel. It would run for a bit on what is in the carb and lines before it got to what you put in, and the scenario fits . . .

Is this a 2 stroke or 4 stroke engine?

Thanks! I'll drain out the old gas and see if that helps.

It's a 4 stroke engine

Welcome to SBF Jessica. I would also try a new spark plug after you drain and refill the gas tank. Does the starter rope feel the same when you pull it, or is it easier? Any unusual noises?

Toro 8/24 (38080) 1989
Toro 721-QZR (38743) 2015 (Hemi Predator Power)
Toro (51984) Hand Held Blower (For the light stuff)

Experience is something you don't get until just after you need it.

Thanks for the suggestion! Spark plug was on my list to check. When I was trying to start it after it stalled, it seemed like maybe the rope was pulling easier. No weird noises though.

Just to rule out a broken connecting rod, stick a soda straw or a pencil into the engine cylinder after you remove the spark plug and pull the starter rope slowly to see if the straw\pencil moves up and down. I hope it does.

I will definitely try that! Is the engine cylinder where the spark plug goes? Or am I looking for something else?

Yes, the cylinder is what the plug tip is inside of. Other than some older engines, the plug is typically right above the piston (which you will see if you look in the plug hole).

So I just checked it over. The connecting rod was good. Spark plug was good. Emptied out the gas tank and put some new gas in and it started right up! So old fuel was my problem. Thanks so much for all the help!

Sounds like there’s a possibility of a sheared key in the keyway in the flywheel. This would through off your spark preventing a start. You’ll have spark at the plug but timing will be off.
