I wanted to take a moment to followup on a conversation a couple of weeks ago about some problems I was havin with a JD M fouling the plugs.First let me say thanks to all those who replied! My problem seemed multifactorial(as most are) I took off the resistor and made sure the 12v coil I had purchased was the proper one. Next I changed the condensor to a 12v, changedf the wires to actual wire core instead of that other stuff, changed to H12 plugs and lastly adjusted the valves to .08-.10 (they were pretty tight, now I have just a touch more chatter but it's hardly noticeable - they hadn't been adjusted since the new haed/valves were added earlier this year) While looking over the entire air intake/carb system and attempting to adjust the carb to be more lean, I noticed that in order to get that classic two cyl idle where you thinks its going to go dead I had to adjust the idle screw significantly. This prompted an investigation of the carb and governor linkage which turned out to be a problem. Sometime ago in this tractor's life, the throttle to gov linkage adjustment had been broken ad only a fwe threads remained(enough to hold it place butnot allow any adjustment) Anyway, after welding on a machine screw to the end to duplicate the gov age rod on my other M, thigs seem to be working great! I haven't run the tractor for over 2-3 hrs and without load but a quick glance at the plugs show no sign of fouling so it was probably a carb problem of running to rich but I'm glad I did all the other stuff anyway! Thanks again for the help and I'm about to post a new question about a 720LP clutch I'm working on so any help is again appreciated Merry Christmas to all!!
