I've been fooling around with Farmalls for several years and thought I was pretty good at working on the old stuff until I started working on the timing on my old 300 RC. The guy I bought it from many years ago, had rebuilt it but had it timed backwards. It allways ran great so I never changed it back. Lately it started acting stupid so I started investigating. Changed points, condencer and plug wires, (plugs were good)but it still ran stupid and was hard to get started. Changed coils, but no change. I pulled out the distributor, and found the drive gear loose on the shaft. Changed it out with a good dist. unit, got #1 to TDC, set the points, went to fire her up,,,,, nothing. Scratched my head, rechecked everything, bought a new horse honking battery, (thought the other one would not take a charge)started again,,nothing. Checked the shop manual, found out the hundred series tractors had several different distributors, an O, a S, amoung others, and each one set to a different timing mark on the crank pully, not TDC. The one I had replaced the original one with was an "A" which is for a C248 engine, not the 169, and the book says set it to the 2nd mark. So this evening after work, I will replace the "A" with an "O" and set it to the second mark and hope for the best. Why all the different marks anyway? (different degrees of advance)
