My venerable work horse has been difficult to start at various times since purchase four years ago. Have rebuilt then replaced the carburator, performed a tune-up about 3 yrs ago, and most recently replaced the battery. Still no go. Checked the spark plug wires and they seemed OK and worked my way to the distributor cap. The rotor looks OK but one of the contacts in the dist. cap is almost 80% gone, but the other three contacts look OK. What does this mean (besides the need to replace the dist. cap)? Is one of the plugs arcing inside and drawing current? Is it a hidden flaw in one of the spark plug wires? Does the rotor have to be replaced if it looks OK? Is it the fault of my bad karma?
When I was able to start it about three months ago the engine did not run rough.
Thanks

Sure you have the cap on right? There is an offset tab in the cap that fits in a square cut out in the distributor body. If the cap is not in the correct position it will be slanted.

I don't know about you but I NEVER replace the condenser unless I feel it is bad. I have had more bad ones come from the factory than I have seen on equipment.

You did not REALLY do a tune-up,or you would not have trouble now. Replace plugs, points, condensor, rotor cap, distributer cap, plug wires, set timing. You will see NEW tractor, easy start, more power, less fuel, and last much longer. Don't tightwad on tuneups, lubricants, and filters. Cheapest money you ever spent.

As long as valve clearances have not been neglected, and gone to less than zero.

Rotors can look good and be junk I have that problem with one tractor all the time. Also when replaceing the cap you should always replace the rotor
