I rebuilt the Marelli distro, it was caked in grease and the shaft was sticking because of the shaft grease had turned into glue,,,,,,,typical stuff.

Purchased the rebuild kit from one of our best vendors, and when I went to replace the springs I noticed that one was very different from within the kit. Sooooo, either the kit is wrong or the previous owner/mechanic/factory used a different spring formula.



The ones on the left are the same, each are in good shape, the ones on the right are VERY different. My guess is that the advance curve is designed to be smoother through the arc of the engine RPMs, where one side of the two weights advances first and then the other. My concern is that the stiffer spring is really stiff, even on a log scale there is a long way between these two.

Any ideas as to which is the correct one? (Yes I did triple check that I had ordered the correct kit.)
