First, I want to thank everyone for all of the help and suggestions.
The latest update is that I do not get any spark from the coil. I put the old coil back on and couldn't get any spark from it either. I took a coil off another engine and couldn't get any spark with it either.
With the ign. switch on, (but not cranking the motor) I have 12 volts from the positive terminal of the coil to ground. I also have 12 volts from the negative terminal (which is connected to the outside distributor terminal) to ground. John T says this should not be, but with the coil disconnected and sitting on a bench, there is only about 1 ohm resistance across these terminals. So, if you have voltage on one terminal, how can you not have it on the other?
I will replace the cable from the distributor cap to the coil tomorrow, but I don't expect that to work either.
I have had the tractor for 10 years. I put about 50 hours a year on it and it has always run well, but now I'm thinking I have spent more time on it than the thing is worth. If the new coil cable doesn't do the trick, I think I will disassemble the tractor and sell it for scrap iron.
