Used my cub for disking two hours,ran fine. Drove it on the trailer killed it. Eight mile trip home(smooth highway)tried to unload wouldn't start. No fire at the plugs. Pulled coil wire and held it away to check coil and it fired right up. Pushed wire in place and it dies. Checked coil with ohm meter - 1.3ohm maybe a little weak. Drove 30 mi to Case IH new coil,points & cond. Same results. Drove to parts store new plugwires same results.Had old rotor tried it ,same thing.By this time I was ready to drive to one of the fires and push it off the trailer.Back to case IH new cap and rotor fired right up. What gives?

Check the little wires, at the connections, and even a break in the middle will drive you nuts. I had one that was broke where it goes in the insulated piece going into the distributor, wiggle it one way, it ran, wiggle it again, dead. Ones in the box to and from the switch too. That's too cute, cure might be too easy...don't arrange an accident for it yet. you are near the fires? Get this thing fixed, I heard discing everything a couple hundred feet around your buildings is a good start for fire breaks, be careful down there, good luck with the cub.

Hal has the correct answer. A carbon trail on either the cap or rotor can divert the spark so that you will not get a spark at the plugs. By pulling the coil wire out a little it raises the voltage from the coil so that the carbon trail cannot discharge all of the spark so some of it also ends up going to the spark plugs.
