Lovehamr has the solution. The tang on the rotor must have firm contact the carbon post located in the cap. PERIOD If you bend the rotor tang toward the cap with firm contact you will not have any problem. I use Wells or Blue Streak caps and rotors because they are much cheaper and you can get the copper not aluminum terminals. MSD red is very identifiable but these other guys offer old school black distributor caps, good for an extra 5 MPH at least! or like he said .... "Others like Ron (and me) have ****e canned the whole thing." works too !! LMAO
