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?
