I have a JD40 distributor (Delco Remy 1111709) that the advance springs (1901737) are missing on. Does anyone know of a compatable modern spring to replace them with? According to Delco they no longer stock the part and the only ones I have found elsewhere are about $22.00 apiece, which I refuse to pay for a 1/2 inch spring.
Sounds better than $20.00 :-) My problem is that I don't know what spring kit may be compatible and I don't see any way to tell by Pertronics web site. I would suspect that being only a 2 cylinder, the tractor is sensitive to spark advance. I sent them an email asking if they know what may be compatable.
