Hello:

Have a practically brand new Ariens snow blower with a Tecumseh engine.
Used just a few times last year; worked perfectly.
Having a bit of trouble this year. First time used this year, as we
haven't had any snow to talk about.

Starts right up, runs just fine for 5 to perhaps 8 minutes, and then
stops.
Easy to start again, then same thing: 5-8 minutes, and stops.
And again.

Not clogged.
New gas.

Doubt that it needs a new plug, as it's been used probably no more than
half a dozen times since bought.
Think it can be gummed up already ?

Anyway was wondering if this "runs and then stops" symptom, for all you
engine experts out there, might suggest what
is wrong ?

Thanks,
Bob


Possibly a plugged gas tank vent. However, if the engine starts up well
immediately after a stall, the logic for this analysis fails. With a time
lapse after the stall, an incomplete blockage might pass enough air to
permit another run cycle.
