Ignition Issues, Crab distributor

[Ziggster]

I just went through this entire thread. Lots of good info. I’m in the process of resurrecting one of my crab distributors to test on my Allen Syncrograph machine. I can say the following:

1. No play or “grabbiing” on my advance plate.
2. Both the pistons I have for the vacuum brake fit nicely with no slop.
3. Cleaned up ALL electrical contact points with 600 grit paper. Thus includes condenser tabs, main ground stud nuts, distributor hsg where condenser mounts. Contact area on main plate for spring loaded ground stud. Of course breaker points cleaned, rotor and contact points cleaned.

Questions for you:

1. I’m running the same cam in my C59A. What is your advance setting on the distributor?
2. What conditions are the csm lobes in?
3. Did you lub all the contact surfaces for the moving parts?
4. What condition are the rotor contacts points in?

I watched this vid to help me. He says folks run no vacuum brake without issues.
