Not sure how it broke. I was blowing and it just started to run like crap. Took the shroud off to check the carb and noticed the muffler didn't look right. One bole broke at the point where the threads stop and the shoulder stops. There was enough sticking out that I could grab it with vice grips and take it out.

One of the two bolts that hold the muffler onto the engine of my snowblower broke in two pieces. It's a 10 hp Tecumseh L-Head, if it matters. Do I need to go to the outdoor power shop and get special bolts, or can I go to Home Depot and match the thread and length and be done with it? Thanks in advance.

I'll try the gas cap thing.  I doubt it's bad gas. The machine has had 15-20 tanks of gas run through it this year, being that we live just north of Syracuse, we get a lot of snow.

I assumed that if the coil was bad, it wouldn't spark correctly at all. Thanks for the suggestions. I'll update after the next storm.

Hello all, long time reader first time poster and such.

I'm having a problem with my fathers snowblower, it's a 3 yaer old mtd(I know) with a 10 hp Tecumseh L-head engine. It will run fine for about 30 to 40 minutes then it will start surging and stall. It won't start again until it's sat for an hour or two. I'm assuming it's cooling down. I changed the oil and the plug and it seems to run great right until it stalls. It does it in all temps and in both powder conditions or heavy slush snow.

Any ideas on why it's doing this? Thanks in advance.

Matt
