I need some feed back to understand why the distributor on my 1929 AC International Chevy moves while cranking it over?

I have not removed the distributor but did check the timing at 12 degrees tdc on the compression stroke.

Essentially, I adjusted and cleaned the points and now awaiting an ignition tune up kit.

I noticed there is a spring attached to the distributor and the fuel pump. It was pretty stretched out and have not seen a spring set up on a distributor like this before until now. So, I have removed it and not replaced it.

I took off the spark control linkage to make sure that the there was nothing affecting the distributor.

The only cable to the distributor is the electrical lock ignition cable.

Baffled and need help on solving this problem!!

I have to give credit to Skip for walking me through some issues with the distributor movement.

I found that the distributor cable wire clamp was broken. I has a friend come over and one operated the starter button, and I watched the distributor movement. I watch the wire housing move back and forth and not the distributor.

Skip explained to me that the wire clamp needs to be tight to prevent the wire housing from moving.

I repaired that and reset the cable length correctly to get more movement from advance to retard position.

The most important piece of advice Skip offered was to set the timing to 18 degrees TDC on the compression stroke, and move the distributor body to line up with nbr one cylinder.

The increase in timing is due to the octane rate we use today.

This begs the question of how many other antique cars are in the same predicament with high octane?

By "distributor cable wire clamp" are you referring to the to the conduit that the manual advance control travels through?

Thanks, Lou

Thank you for bringing up the clamp.

I am talking about the small cable that has the wire going through it to advance and retard the spark. The clamp is the small clamp that hold the cable in place.
