So I'm having a strange ignition issue with the 153 in my CJ2a. It has a miss, and in checking the timing I noticed the timing light does not fire consistently on the #1 cylinder. I put the light on the other cylinders and they all seem to fire the light consistently. The #1 plug is black and sooty, the other three look normal. I swapped the plug wires between #1 and #2, same result, (#1 is still inconsistent, #2 is normal). I'm a little baffled by this as the cap and rotor look fine. I ordered a new cap and rotor anyway. I put a pertronix in this distributor about 4 years ago, could it be failing? Question: My spare motor has an HEI distributor on it. Can I just swap that in? The only connections I see on it are for "BATT" and "TACH". Can I just give it 12V from the battery and run it? Doesn't it need a ground like the older coil has?
