It is running lean and/or the exhaust valve needs adjusted.

Please direct all snow blower questions to the forums and not to me with PMs.

How old is the muffler? Is it rusted? Gasket where muffler attaches may need replacement (with a new muffler).

If valve lash is ok, too lean. Is the muffler red hot as well?

I had sparks coming out of my muffler. I replaced it along with a new gasket and no more problems. That's an easy starting point.
