Long time Ford tractor guy here but I inherited my Dad's 1963 2000 tractor and it is giving me fits. My Dad is not much of a mechanic, so this poor tractor has been neglected a lot, and sat for years due to not running good. It was converted to 12v before my Dad got it. I first changed the oil, new plugs ponts and condensor, rebuild the carb 3 or 4 times trying to fix this stuttering issue. Governor is adjusted per the I&T manual. It now starts immediately even on low throttle with no choke. Compression is right at 115 across all cylinders, low but workable. It smokes bad out of the oil filler cap and valve cover vent but no white or black smoke out of the exhaust pipe. Soaking the cylinders with MMO for several days did not help this blowback.
When I drive it there is hesitation, sputtering, and sometimes the engine shuts off like you turned the key off but catches again before completely dying. Spark plugs are dry and sooty like I am running rich but carb is set to 1 1/4 turns out from seated and if I lean it out more it pops and runs rough. I bypassed the new keyed switch with no improvement. Starting to lean towards ignition now. The round 12v coil has a weird extra item mounted externally that looks like a condenser connected to it - not sure why this would be there or what it is (?) Should I remove this?
Any ideas?
