Magneto timing

Posted by Don Mountain on April 12, 2013 at 06:49:22 from (184.5.199.73):

I have a 1954 Farmall Super C tractor with an H-4 magneto that originally was on my Farmall M. I had to replace the coil in it several years ago when I mounted it on the Super C, and it seemed to run fine, but I couldn't time it properly. Yesterday I replaced the points, capaciter, and rotor in it and still have the timing problem. When I turn the engine over to Top Dead Center mark on cylinder number one, and I try to rotate the magneto to the point where the impulse coupler fires, I hit the limits of movement before I get there. So my magneto is turned so the top is away from the engine block all the way to the limit. If I start cranking the engine, the impulse coupler fires just maybe 5 degrees away from Top Dead Center. Is there a way to fix this so the Top Dead Center position occurs somewhere in the middle of the ajustment range when the impulse coupler fires? Or should I be timing it some other way?
