When I had a similar issue with my 210 it turned out to a wire going to the coil + side was making contact with the engine tin, causing it to ground out.
I’d check the coil, condenser, and points. Good luck.
thanks everyone for the replys. here is what i have found... i cleaned and gaped the points. the points are only a year old. i was cranking it over and saw that the spark plug wire by the boot on the coil was sparking to the frame of the tractor. i figured that was what was wrong so i changed the wire. it did stop sparking but did not solve the issue. so i gave up for a little while and worked on some other stuff. i thought i heard my neighbor watering his flowers. but glanced at the tractor and noticed my coil was smoking and leaking. i dissconnected the battery and it stopped. i checked the battery voltage and it was 18 volts!!. so my question is, would that be the source of my issues? like i stated before it ran great when i put it away. what else would i of hurt besides the coil. Thanks
