Thanks W8YE feels better knowing the engine is alright. I am concerned, however about the heat that was high enough to melt the plastic and that it apparently came somehow from the carburator. The plastic piece that the carb it bolted to also melted around the carb, but the back plate does not seem affected at all. Also, my throttle round thingy that the throttle lever was mounted to also seems a bit rough probably order one of those too.
compression is now strong.
