Default Re: Engine wont turn now

If the engine doesn't turn over with spark plug in make sure the tip of the spark plug isnt getting hit by the piston on the compression stoke. A easy way to check this is to put the spark plug in the head and put the head on the engine all the way on with out putting the acorn nuts on. Slowly turn the engine over and see if the head lifts off the cylinder at all , if it does than the plug threads are too long. If you have the original plug and head you should not have this problem.

Did any of the cylinder wall plating flake off from the piston seizure? What oil ratio are you running too?

When in doubt Throttle out!
