I am utterly tearing my hair out of my scalp. This is a craftsman snowblower with this engine and it is very low hours and use, most likely because of this issue.
It will run for quite a while 15-20 minutes then pops, spits like it is fouling out a plug or loosing spark It is NOT!!!!!!! The moment it dies I can test and it has a nice bright purple spark.
Its almost like it cant draw in fuel properly or heat locking the fuel system. If you blow into the gas tank it will start back up run for a short while then die back out.
I cleaned the tank, removed the filter screen and cleaned it, and also cleaned the carb and emultion tube. I also enlarged the main jet to stop the hunting, and it actually helped prolong how long it runs. Leaving the gas cap off makes no difference, and the cap vents just fine.
What is causing it to not meter fuel correctly only when hot?
