FM J4B73 mag Ford 4 cyl L Head. Had always had my mags rebuilt by a local shop but the guy who did it retired. He always set my mags to fire on #1. I shipped it off to be done got it back mounted it brought #1 cyl to tdc, tractor wont start all wires where they belong, got plugs out they fire great 1-2-4-3 but not at the right time.I called the mag shop and asked him if he had set the mag to fire on #1 tdc, he says dont need to on a mag you just "move the wires around" till ya get it to go.I ask aren't the rotor and drive shaft timing marked to bring a mag to fire on #1? Next I say why then do they have the cyl #s on the cap------he says I have no idea why they bothered to put cyl #s on the cap. Next ? again to him was why are the shaft and rotor marked to time the mag,he gave me a reason which I could not understand and at that point I wished him a good day. I know how to time the drive and rotor with #1 tdc.Being curious is why I post my ? is he in line with other mag repairmen, and why did the manufacturers of the mag put cyl #s on the cap, I can only come up with one answer.
