Right on both counts. When the points are closed, the voltage on the distributor side of the coil goes to zero. The cam in the distributor should open the points 4 times per revolution of the distributor shaft. When the points are closed, current flows through the coil and sets up a magnetic field. When the points open, the current flow stops, the magnetic field in the coil's primary winding collapses, and creates a high voltage in the seconary windings. That give you the spark. Your distributor bushings or shaft might be worn out, that could let the shaft wobble around. You can set the point gap on any of the lobes (corners) of the dist. cam. If you set the gap on the #4 firing position (opposite #1), will the points close on all the flats ? If so, you might be able to get it to run that way. If you have a belt pulley, you can use that to turn the engine over. With out a belt pulley or a crank, you can put the tractor in 5th gear and push on the rear wheel to turn the motor. In either case, it is easier with the plugs out. Tanner, I'm curious, how old are you and what was your first car ? Greg

The garden was already sprouting when we hooked up the mid-mount shovel cultivators to the Pony. The seed bed was soft enough that the rear end would spin and slowly work its way to the downhill side of the gardens slight incline. From this, we learned our lesson sinc
