Chainsaw Repair

I hear ya on the vent.   I think we have all had a simple problem byte us in the butt.   I had a 2 cycle engine at work one time that would run really good for about 5 minutes and then it would get hot and then just stop.  You could not get it to restart for nothing.   Even priming it through the carb I could hear the fuel sizzle inside the engine because it was so hot.   After it cooled down for a couple of hours then it would start and do the same thing all over again.  Turned out to be the fuel filter, but not before it faked me out big time.
