White snow boss 50

Snow blower will start on the first pull and run for a minute or two and then shut off. It then has to sit for another few minutes before it will start again. I've played around with the choke and it has new gas. Is it getting flooded, and how would I fix that?

Thanks for your thoughts.

What makes you think it's being flooded? Are you leaving the choke on for the whole time until it dies?

I don't think infected but I think there may be a restriction in the fuel line or a problem in the carb. It sounds like fuel is only very slowly getting into the carburetor's bowl. If let sit the bowl fills and the engine will run until the level in the bowl drops too low. At least that's my guess without knowing more.

Yes, I would suspect the same thing, so would start by removing the bowl, float, and needle, cleaning them thoroughly, and reinstalling. I would not remove the seat, but would spray carburetor cleaner around it as well, while the needle is out.

If it's not blowing black exhaust, it isn't likely a flooding issue, but rather a lack of fuel. Normally an engine will speed up a little just before it dies, as it runs out of fuel = leaning out of mixture.

Any part of the fuel system that delivers fuel to the carburetor as well as the carburetor itself could be at fault

If it runs OK for a couple of minutes, I doubt if it has dirt in the jets, but possibly in the float valve, or the lines leading to the carb, or in the outlet of the tank, or possibly a plugged fuel cap vent.

Try running it with the fuel cap loose. If that doesn't help, disconnect the fuel line from the carb and let it drain out into a container. It should have a good steady flow.

If you have a good flow there, and you have a drain nut on the carb bowl, take that out and let the fuel run through the bowl. You should have a steady stream of fuel out of the bowl nut hole.

Thanks for your thoughts.

How old is this unit? What engine ? How long have you owned this unit?
What do you mean "played around with the choke" ??
When was it last tuned up ... new plug?
When it shuts off does it have spark when you try to restart? Does it smell flooded ?

My thoughts are we need quite a bit more info before we spend much time spinning on a bunch of unknown info.

All the best.
