Rotor breaking

Farmer Bill

The best bet to check things out is to remove one of the coil wires (so the tractor can't start) and spin the engine with the starter. See if the distributor cap rocks back and forth as the engine goes around. If it does, the rotor is hitting the cap. That's how I found my rotor was not pushed down all the way.

With your chronic problems, you could take this a step further. Remove the distributor entirely from the engine, assemble the rotor and cap, and spin the drive gear with your fingers. You should be able to feel the cam open and close the points, but should not feel any dragging or grinding from the rotor interfering with the cap.

2nd rotor would have taught you to be certain that the rotor is seated in the distributor shaft notch. 3rd rotor definately make certain the distributor shaft has no end play and the rotor is in the notch. 4th rotor, you're eather a slow learner.....or..... you've got an incorrect distributor cap. Do I have to tell you to get a new distributor cap?..... ....respectfully, Dell

As you now have learned, the side mount 8n and the Naa, and hundred series dists. use a "Spring clip" under the rotor , this spring clip is of a poor design(You know how some engineers are when designing stuff ) and the said "Clip" will sometimes fly off when serviceing the points,cap and such, this has nothing to do with ones "intelligence" !

It's a design flaw from some self centered engineer that us "Working" people have to deal with !

What if his rotor's too long?
