Ignition Issues, Crab distributor

Well, You hit something I think, did a second stress test today, started surging a bit, few hundred rpm, then started this light clattering from the front of the motor. Then it died, I did find when you block the vacuum to the distributor it dies.

Pulled the distributor off when it was HOT.

Curse words were said, but the advance was sticking when hot. once it cooled down the advance worked smooth like butter. I had a advance off another distributor here, so swapped that out, then I was looking at the vacuum brake, the piston fit a little loose in bore, you could rattle it side to side a couple thou. Checked the other housing I was scavenging from, NO play.

So I have cleaned, built another distributor out of some parts etc.

Wish Bubbas was still around, Id just send the distributor to him and let him do his voodoo magic to it. But maybe I have found something. FINGERS CROSSED>

Hope everyone had a good weekend!

Took the advance apart. This looks a bit rough but I don’t have a lot to go off of on experience on these advances. Shaft kinda binds a smidge going in and out of the weight plate.
