Thanks Bob & Jerry for your quick responses. Replaced a bunch of old wiring yesterday, tested ignition switch, etc. Attempted to start after each process. Achieved immediate success after changing out the points. Unfortunately, it"s the wettest summer ever here in Oklahoma (rained almost every day since June 1) and my property is too soggy to mow. At least now I know the tractor will start when it does dry out. Regarding the recommended 13.6 V charging level, my dashboard ammeter shows just below the 15 V mark when idling (the gauge has 5 V increments). When the engine"s revved up, the meter jumps up substantially. Haven"t checked it under a load yet. Pulled, inspected, cleaned the spark plugs, which were Motorcraft BTS10 (haven"t had a chance to get new ones yet). All except #4 looked good (relatively speaking). #4 was quite oily with alot of hardened black deposits. I doubt if it was even firing. Anyway, after cleaning it up and re-installing, the engine ran smoother. Re: the Petronix system, is this something my local tractor supply or auto parts stores will carry? Or do you have to buy it online? Also, will I need to convert from 6 V to 12 V for the Petronix to work? Thanks in advance gentlemen for your advice.
