Hi all, I have a 2 year old 9 horse Tecumseh motor craftsmen snowblower, starts great and runs for about 3 to 5 minutes then begins to stall, wait a few minutes and it runs great again for a few minutes and does it all again. Seems to run gas out of the float bowl, then it sits and fills up to run great again. this is only my guess, how does it sound?

 

Could be the fuel cap not venting properly. Try running it with the fuel cap loose and see if it will continue to run. Sometimes I see on Tecumseh engines the "guts" fall out of the fuel cap and then when tightened onto the tank, they seal so good they don't let any air in and a vacuum is created.
