if you can wait, get yourself a good magneto restore book to guide you thru a check/restore. when we get impatient we make mistakes! if you must go on, as mentioned before, take the magnet off to see if it is strong, also check to make sure the i h c symbol on the magnet is facing you as you stand next to the tractor (right side). when you take the magnet off and leave it off, put it on a piece of soft steel to keep it magnatized. a friend of mine decided to clean his magnet on a wire wheel, when he got done, the magnet was dead. check the bearings for excesive side to side and end play. of course, check the points for corrosion. go to a office supply store and get a hand full of ink pens with the white erasers on top. those erasers make good metal cleaners instead of files. use the files to level the points. make sure the timing lever is not all the way up (in the kill position) when you check for spark. clean the brown disk (distributor) with a clean cloth with a little kerosene (penetrating oil)on it, and use the ink pen eraser to clean the brass inlay on the brown disk. there will be a punch mark on the brown disk by the gear teeth, it should line up with a flat place on a tooth on the metal gear below. if you have to replace the coil, you will have to take the soft steel core out of the old coil and put it in the new coil, the steel core fits very close between the poles. "do not" alter the surfaces to make it go back together easier! be patient, it will go together. use good tools at a good work area where you can work undisturbed on a comfortable bench with good light. a couple of coffee cans and an old ice tray would be nice. only use the tray for parts you're using at the moment. the other parts go in the coffee can. an old bath towel is nice to work on, the small parts won't bounce or roll around. can't think of anything else right off the top of my head.
