So I heard a slight ticking coming from my engine when I fired it up for the first time this season... figured I needed to do a valve adjustment. Tried removing the crankshaft access bolt to turn the engine to TDC and couldnt get it off. It was stuck hard.... I ended up finally trying an impact wrench and stripped it out entirely. So now the whole side cover needs to come off, and its stuck on hard too! After much pulling and I finally get the side cover off.... and find a ton of melted black plastic inside! The plastic piece that holds the stator wires in place was just a melted lump and there were plastic shavings everywhere. Also there is a baked on film of black plastic on the edge of the flywheel... is it supposed to be there? Any idea what could cause this?
