I have a [Bnew[/B] Craftsman 24" Model 247.889571 snow thrower that runs only 30 seconds and then stops. Have FRESH gas, cleaned plug. Any reasons for it not running?
Thanks

more than likely a dirty carb

New as in brand new from the store never before been used? Or new as in used once 3 years ago and then parked?

Is the oil full?

Are you trying to use it on an angle?

Is one of the safety switches killing the engine?

New THIS YEAR. Used it twice with no problems. Oil IS full.

Could try loosening the gas cap. Maybe the vent is iced over.

I just tried starting it again and this time it ram for over a minute and then stopped, emitting a lot of oily smoke as it shut down. Would not start a second time.

Is the exhaust actually oily, or perhaps sooty might be more accurate? Perhaps the choke is stuck on?

 

[grandpabear]

The exhaust is oily (and smells "oily"). The choke seems to be working when I can get the thrower to run long enough to close it.

oops, missed that "new" part.
Just a thought, how is the oil level? Almost sounds like it could be overfilled.
