Default Re: stumped! any ideas?

Have you run a compression test? A quick way to do it is to pull the coil wire out of the distributor, ground it, and crank the motor with throttle wide open. You will hear a change in cranking speed for lower compression cylinders. We do a quick test on many motors this way.
