I tried some 110 with no effect and I pulled the MSD chip with no effect then I decided to check the 6 month old Cap and rotor that I figured wasnt an issue. The small ball that rides the rotor tang was burned flat and there was a large burn spot on the tang. I only had another used cap and rotor to try but it made an instant difference. I'll get a new cap and rotor this week and see if thats it. What would make an MSD cap/rotor go bad that fast??



It could have been a slight gap between the ball
and rotor to cause a arc.... or alot of tension
on the rotor and ball or if it had moisture on it.
Glad you found your problem.... how long has it been
in there




Moisture my be the culprit with the open hood, it is not sealed to the carb...the cap was only on six months old but I drove the car in damp cold weather early in the year.
