Hello,
I purchased a used snowblower last year with a Tecumseh engine. It starts on the first pull and seemly runs fine at first. After about 20 min of use it starts running rough and sparks start to fly out of the exhaust. The muffler is glowing red. The snowblower then stalls and will not start until it cools down.
Here is a video of it running:

I replaced the ignition coil last summer and it didn't make a difference. I just cleaned the carb as the logical next step.
Any other tips? I read a few posts where there could be issues with exhaust valve lash or head gasket issues. Rather not dig that far if I don't have to.
Thanks,
--Ryan
