Old points distributor advance problem.

Hi!

The oilpump on my almost newbuilt 402 stopped spinning, a piece of one of the gears came loose and made them stuck, very strange.

So my HEI distributor become crap, and in order to use the car until I have a new MSD probillet I installed an very old distributor with points.

The engine runs well @ 14 deg advance @ idle.

When reeving to 4000 I got about 35 deg.
When reeving 6000 I got about 45-50 DEG!! How come?!?

I need to figure out how to make the final advance less,
I want about 34-36 deg max advance for this engine.


Anyone who knows how to modify the advance of this old piece?

I have the vacuum disconnected permanent.

thanks in advance

There is a peg in a slot in the advance mechanism that controls the amount of advance. You should be able to see it with your rotor removed. There are different size bushings that fit over the peg to limit the amount of advance. I suspect the bushing is missing on your unit.

Also make sure that your base plate does not move. I always leave the old vacuum unit installed to hold the base plate in position.
