28 Buick Dist advance degrees

Recommended Posts

I have installed a 28 Buick Delco # 640J 71082 Dist. in my 27 Buick. It idles perfect but mech. advance doesn't work. I took it apart and cleaned and greased it. The plate inside says 25 degrees. Is this what the advance should be at full throttle?? I have afriend who has one of the old dist. machines to test it but wanted to know what it should read in degrees. Thanks for any help.

Mark,

Do you how much it would advance on a dist.machine?? Thanks

It sure runs super at idle.

Steve

I would expect that to be the retarded setting at idle.
