Seems I might be on the market for an 80cc 2-stroke engine block. I had a mounting bolt break off inside the engine block and all attempts to get it out have failed. It's headed to a friends, if he cannot get it out I'll need a new block. Anyone have just the block, I don't need the carb, muffler and so on and I really don't want to have to spend $150+ on an entire new kit.
