It's a 12 volt system. I switched spark plugs and wires, #3 and #4 cylinders, still erratic on #4. So wires and plugs seem ok. I think the problem is with shaft play which I just measured at 0.005" or more.
Distributor cap contacts look rough, particularly the one for #4. It also apparently moves up and down a quarter of an inch because the wear on all the is about that long.
the cap and rotor are fairly new. I"d say much less than 100 hours on them.
I understand this distributor, which I think is original has a bushing at the bottom of the shaft and a ball bearing at the top.
I put the electronic ignition in because I was getting two spark plugs firing and two not because of unequal opening and of the points. In other words, I couldn"t the timing right. It solved that problem, but still needs good bearings and shaft to distribute the spark effectively without chewing up the rotor and cap contacts.
I know I can buy aftermarket distributors. Where can I get mine rebuilt and how much would that be?
