My Magneto advance doesn't work
Posted: Tue Jun 10, 2014 7:12 pm
I have been following the discussions in several threads about setting up the governor and the governor to carb connection. This helped me get a new-to-me 1950 cub running smoothly.
I have a magneto that I static timed. Now I can start the tractor with the hand crank ! I did attach a timing light just because I have one and I need to justify keeping it around. As I moved the throttle, the notch on the pulley did not move at all.
I looked at the Engine Electrical manual and the Magneto manual but I did not see anything about the advance weights. The magneto manual on this site doesn't list the J-4, but I thought they may have something about the weights in general.
Is the magneto "easy" to disassemble to get to the weights? I did open the mag to replace the points and condenser as well as the rotor. I assume that the advance is numbers 50, 51, 52, 54 and 55 in this picture. If I remove the end plate number 53, will tiny parts come flying out? Or do I get at the weights by removing numbers 30 - 37 ?
