Acting on advice from the board, I replaced all battery cables with hairy 2/0 cables and had the starter overhauled because of slow turnover. I purchased tuneup parts from the supplier on the left side of the board. New battery, plugs, plug wires, points, condenser, distributor cap and roter. The engine turned over nicely, started, and ran for a short time (badly), and wouldn't re-start. I pulled the distributor cap and noticed brass shavings laying atop the dust cover, but couldn't see any marks on the contacts of the distributor cap where the rotor may have "scraped" the contacts. Replaced the cap and tried to start again. Nothing. I pulled the distributor cap again and found that the rotor had broken in half, obviously from hitting the contacts in the cap. I put the old distributor cap and rotor on and checked the spark which seemed yellow and weak. Tried the starter and the tractor started right up. Went to work pulling a tree from the woods and the tractor simply stopped running after about 15 minutes. It started up again, but would only keep running (badly) if I played with the choke. This began to sound like a bad coil so I went to town and got a new one. The coil was stamped, "12V must use primary resister wire or resistor in system". The mechanic at the shop said this meant that if the coil was used in a 12V system that a resistor was needed, otherwise, not. Since I have a 6V system, I installed the coil, treated the carburator to a carb cleaner bath and tried the starter again. Fired up and ran immediately. I ran the tractor for about 45 minutes, doing light work and it ran well and was able to idle at the slowest possible throttle setting, which it hadn't done before. So I have three questions, and solicit opinions. 1. Should I contact the supplier of the cap and rotor. They obviously were not matched, unless there is some other reason why the rotor broke. 2. Was my starting problem really the coil all along? 3. Will the new coil fail if I do not have a resistor in the system. Thanks for any opinions.
