Does not start no spark.
several moths ago popped tire. ran a little rough at that time. took several weeks to get tire fixed, after that it didn"t start.
there is no hood on it and it got rained on after tarp blew off.
replaced the ignition switch and the starter drive gear and eliminated the charging circuit as these were issues before and made it hard to troubleshoot spark issue. now starter runs strong and battery is fresh charged. the main starter terminal is not the best but i got it to work after some futzing. seems to have good contact now runs real fast. will be replacing it but it is not touching the casing now (checked with meter) and reasonably tight to the coils inside.
its wired 12v negative ground. not sure how many parts were originally 12v, was made in 1957 and it had a 12v generator on it when i got it. now it just runs on the battery.
i measured 12.5v at + coil and - coil with key on; then while starter is turning drops to 10v.
the ignition coil was replaced, the old one the terminal broke inside when i was troubleshooting (cleaning and tightening connections). new one came from tractor supply says 12v no resistor needed (and i don"t have a resistor).
added all the parts from the tractor supply farmall tuneup kit (cap, rotor, plugs, points, condenser) no help
checked the point gap several times. a little play in the distributor making it hard to set.

As simple as a box plow appears, it can be rather challenging to make work correctly. In our sandy soils of Florida, traction is king. You can never have wide enough tires or heavy enough weights to get all the traction you want … unless you own a monster tractor. U
