I've got a strange problem. I tried starting the car up last weekend, but it was missing on several cylinders. I didn't have time to mess with it, and since it had been raining for the better part of the week, figured something may just be damp and needs to dry out. I tried starting it today and can't seem to get anything to fire. I've gone all over it and have found some confusing results. My normal test to see if I even have spark works. I pulled one of the plugwires, placed a screwdriver into it and turned the engine. It arcs from the screwdriver to ground. This led me to chase some other avenues for awhile. I came back to the ignition again. Pulled a plug to check the gap on it. They're dead on at .035. I put one of the plugs onto the plug wire, placed it onto ground, and turned the engine. No spark! I held the wire away from the ground and now it sparks! This is a standard points distributor, with a standard coil. The point gap looks good. I've removed the tach to ensure there's nothing interfering with it. Anyone have a clue what could be going on here, and how to fix it? BTW, one of the other things I was checking was compression. What would be a good value for a 350 with 47 heads?
