Glenn F. said: (quoted from post at 23:13:56 07/13/10) About fifteen years ago we replaced the non-functioning magneto on our '51 DC CASE with a "90 degree" Delco Remy distributer we got off a DC in a salvage yard. For years the distributer worked just fine. Then we sent the engine out for a complete overhaul. Ever since, the tractor will not start without having to retard the timing. Upon starting we must immediately advance the timing for the tractor to run properly.
Today we took the distributer all apart, cleaned/oiled it all up and reassembled, but the problem persists. There is no vacuum advance, but some sort of centrifugal advance system. Everything looks good inside, but obviously there's a problem.
Any repair suggestions?
Thank you,
Glenn F.
Look for missing broken spring in advance mechanism. Allowing it to be fully advanced at starting.
Oh, and just for the record, such all inclusive blanket statements as, " Tractors don't use a vacuum advance.", should never be made as they will almost always be in error, as is this one.

My curiosity was up and I wanted to contact the owner. I wanted to see what he planned to do with the combine.
