Abe....Yeah, the volt meter idea is great, except the problem comes and goes, and rarley does it sitting in the driveway. The misfire and stumbling happens when I take off down the road, under load. This makes it kind of difficult to read a volt meter, drive, and shift gears. Not to worry....I'll get it figured out. I'm going to rig up a "temporary ground loop" connecting the motor, frame, chassis, MSD, and battery all to one negative source...and see if that makes a difference. Update coming soon.
Thanks-CJ
