I have a Ford 661 tractor that was running rough. I replaced points, plugs, wires, condenser and rotor and it ran fine pulling a bush hog for over 2 hours even though I just guessed at the points gap since I didn't have a feeler gauge available at the time.
Later after repairing a leaking gas tank and properly adjusting the points gap, it ran rough so I adjusted points again and it ran fairly well for a short period and then died. When I tried to start it it seemed to want to backfire a little. I replaced and adjusted points again and it started and ran for a bit and died like it was out of gas and would not restart.
After checking points I looked at the rotor and noticed that the square side that slides over the keeper clip was chipped. I replaced the rotor with a new one and it started and ran for a short period and died again. The new rotor was also chipped which seemed to create a miss fire or out of sequence fire.
Can you advise me as to a solution or cause ? I bought ignition parts from Tractor supply and the package indicated that it was for the 600/800 series.
Could the rotor keeper be worn thus causing the rotor to slip and then chip?
