I'm not quite sure what you mean your spark plug was jumping everywhere... Was there a tip on it when you remove the plug? If not, you could have snapped a rod :thumbdown

well there was still a tip on the plug but it had been smashed back against the electrode.....and while the motor was running the plug and plug wire were jumping around like the piston was hitting the plug

You jumped timing, snapped a valve head, and yes, now it's trying to hammer its way either down through the piston crown or up into the water passages in the head.

For god's sake, stop cranking it.

Next stop: rebuild.
