im sorry for that confusion.. the clicking i was hearing: the flywheel was loose on the shaft and when the magnets on the flywheel met the ignition coil, magneta whatever it is actually called they clicked against it making it feel unnatural, i didn't investigate at all and i just thought about it while i was typing so i wrote it without looking into the matter.. anyway, there is no play in the crankshaft whatsoever, the engine sounds solid and smooth while running so i think the only problem is just the compression and/or the fuel delivery.
