I didn't think about the diode. The CIH dealer sells a diode with spade connectors but they call it a rectifier. Maybe I'm imagining things, but I get the feeling this tractor is lacking for a strong spark. The owner said it has been fouling plugs so he put in plugs that were one step hotter. The book calls for a champion D16Y and he put in D18Y's. The D18's fouled for me so I put in straight D21's. The 21's don't quite have the reach but they work. This tractor is cold blooded and I need to have my hand by the choke for the first fifteen minute or so after startup, so it's not running rich. It does not burn oil and the compression is up to snuff. When I changed plugs, # 1&2 were very dry sooty. 3&4 were white and clean and 5&6 were just moderately sooty. I don't know if the plug wires are carbon or copper, but they look newish. After I put the D21's in it purred like a kitten at idle and no load but there just seemed to be a not-so-strong sound to the exhaust when loaded. It seems to have power but there is just that certain sound in the exhaust tone that perks up my curiosity.
My first intuition is still telling me the external resister is resisting a coil that has built in resistance. I didn't take the time yet to do voltage readings at the coil. I just wanted to get this thing running well enough to do dirt work this afternoon before we freeze up for the season, and I did get it done. Jim

She smoked terribly and never had much power but he couldn't afford another so he was limping along with what he had. Jon's Allis has a small front loader and though it doesn't carry much, it serves his needs. It was the hard starting and low power that made him think it was time to replace the old girl.
