Ignition problems with pick up circuit

Your gap is too tight if you are correct on the Pickup. You say it is .008,

It should be .080 range.

Sorry MD .008 is correct. However, this brings up a good point........check that the shaft is not bent or other damage, or worn shaft bushings is not causing strike damage. Examine the ends of the reluctor tips

Also when setting gap, the vacuum advance can and does cause this to change as the breaker plate moves on it's pivot
