I have a 420 where the starter occasionally just locks up, i.e., trying to turn over the starter, nothing happens, just get a click. When I loosen the starter and work the housing back (have to take the battery box off to be able to remove the starter) and then re-attach the starter it will start cranking the engine again. At least that worked today; last time, took the starter off and then re-installed. I decided to just try moving the starter back out as far as I could today without removing the battery, battery box, and all.
This has been quite frustrating, tractor died on my son about a month ago while he was doing some work for me. Could not get it to restart. Have been trying to troubleshoot and then the starter starts acting up. Looks like I"m not getting spark. With the switch, I only get 3.5 volts at the coil, bypassing the switch as recommended here gets 6 volts to the coil but still no joy. Have replaced the coil, points, and condenser. No joy. It looks like I"m getting intermittent spark. Then, when I think I have something to try, the starter decides to stop spinning.
