Hey all,
I've got what is definitely a timing issue, but other things may be going on as well. I recently tuned up the tractor - a 1972 Ford 4000 3-cyl gas - replacing the plugs and wires, distributor cap, points, rotor, etc. I thoroughly cleaned the distributor and lubed it as needed; all the parts seemed to be working fine (weights, advance, camshaft, etc.). But I can't get it to the right timing. It seems like I can only place the distributor gear shaft all the way down in three very distinct spots, and even rotating the distributor all the way too the left (most advanced) until it bumps into the carb, I'm still way off time, with an idle of 200-300 rpm (desired 600-700). I'm just seeing the part numbers on the flywheel through the inspection hole, not the degree marks that I want. Also, higher rpms result in rough running, seeming like it occasionally misses a spark or something. I've taken the distributor out and put it back in a few dozen times and am at wits end. Any thoughts? Any way to advance the timing independently of the distributor but get it to be in a spot where I can actually fine-tune things by rotating it? Many thanks in advance
