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
