I just finished doing a total rebuild on my 9N engine. There is one thing that puzzles me about it. Looking at the front of my distributor, the terminals are numbered as follows: upper left - 1 lower left - 2 lower right - 3 upper right - 4 My problem is that in the FO-4 manual it says the firing order is 1-2-4-3 Dist turns CCW If I wire the distributor like that (lower right going to plug number 4, upper right to plug 3) the engine runs like a dog, cant adjust the carb screws correctly and the engine backfires bad. If I wire it 1-2-3-4 (upper right to plug 4) it runs great. I can adjust the carb correctly, it idles good. Could I have some weird cam thing going on? I am assuming that plug number 1 is closest to the radiator and plug 4 is closest to the dash panel. I know that if it aint broke dont fix it but this is bugging me. Maybe it is only running on 2 cylinders? Can anyone help? I am perplexed. Thanks in advance. Joe
