Re: I hate 4 Strokes

quote amuller:

I don’t know anything about this engine. Does it have a cam drive belt that could be out of time? How is the compression? Valve clearances? Ignition timing? (Sheared flywheel key?) Can you tell from the plug whether it’s running rich or lean? Most likely something fundamental is wrong here.

Good advice, I forgot all about this basic four stroke stuff!
