Jim, Take the magneto back off the tractor and clamp it in a vise by the bottom lug. Remove both caps. On the back end of the coil you will see a copper strip that contacts the brass rod coming from the outer cap. With a long handled screwdriver grounded to the case check the spark to the contact.By tripping the impulse you should get 1/2" or more of blue spark. If you have spark you either didn't have the rotor timed right or the spark is going to ground through one of the caps. If you have no spark make sure the points are clean and none of the wires attached to the points are grounding somewhere and try it again. If still no spark, dissconnect the kill wire from the points,sometimes the bushings and washers are bad or installed wrong where the kill wire stud goes through the case. If you still have no spark at this time you might be better off ending it out to a mag shop. You could have weak magnets, but not likely. The magnets holders could have slipped on the shaft (common) or the coil could be bad, or your new. If you find the problem time it up per Dueys post and it will work.

At the end of my post I ment to say, "or your new parts could be bad". I just did a FMJ with a repair kit from TSC and the rotor was no good.
