Alright this is a question for all you mechanics out there. I have a 10hp Tecumseh snow king snowblower that has been on the fritz lately. Blower starts up fine and wil run perfect for about 10 min and then will all of a sudden bog down and stop running. The only thing that keeps it running is when it starts to bog I undo the gas cap and it goes back to full power. It almost seems as if it all of a sudden chokes out. So far I've checked the air filter, changed the oil, fuel cleaner/stabilizer additives, took the carb apart and cleaned it, throttle cable adjustment, choke cable adjustment, checked the belts, drained the fuel and used fresh, spark plug replaced and plug wire checked and checked the ground wire. The blower only has about 15 hrs on it. There is a 5yr warranty on it but I don't want to go thru the hassle of carting it around and having it in the shop this time of year. I'm very experienced with small engine repair & maintence, I'm able to trouble shoot and completely teardown & rebuild my atv's & snowmobile's but for some reason I just can't figure this one out. So if any gear heads out there has any suggestions please let me know!!
