    compression lock B&S 21hp 540cc platium with XRD

    I have been reading about this problem and I understand what you are saying about the jump in movement. Is that p/n for an entire cam or just the relief valve? I also read somewhere about doubling the head gasket to lower the compression, so the starter can rotate the engine. Has anyone tried...

    The model and serial number is on a white label on the engine cover which is damage and unreadable. Is it anywhere else on the engine?

    New starter, battery and adjusted valves to .005 but motor won't spin. Pull plug and it spins fine . External examination of push rods and valve spring movement looks fine. Ideas please
