NE 12v distributor auto advance

[Bob Downunder]

I am restoring a 12volt NE distributor drive for a Dodge 4. The auto advance weights were missing the springs. Does anybody have any information on how much the auto advance, advances the ignition timing. If I can find out the advance curve I will be able to get suitable springs from a distributor repairer.

Any help or information would be much appreciated. Bob

Total amount of advance is 45 deg.

Automatic advance is 25 deg.

Manual advance is 20 deg.

Automatic advance starts to open at 11 MPH

Automatic advance fully open at 42 MPH

Hi Platt- Deutsch

Thankyou for that info, I've converted the MPH figures into engine RPM assumming the 11MPH is a top gear figure, it seems in round figures that the auto advance starts at 480 engine RPM and is fully advanced at 1850 engine RPM. Does this sound about right to you?

Regards Bob.

Sounds about right to me. I have no Tach. so its hard to tell.. That info is out of the owners manual for the car..If you need a coil for that distributor, Meyers has them in stock..They look just like the original..

Hi Platt- Deutsch

I have a copy of the mechanics instruction manual covering vehicles 1914 to 1927 and it doesn't give any manual or automatic advance specs for n.e distributors.Thanks for your reply, I will check out Myers re the coil .

regards Bob.
