I worked on my 52 3600 over the thanksgiving holidays a little. I bought a new six volt coil, six volt battery, spark plugs and wires. But still I had no spark. I checked the wiring and cleaned some of the connections. I am not getting spark to the spark plugs but I am at the points. I think the points are improperly gapped. I am also going to grind the frame at the ground to bare metal to get a better connection. What are the points supposed to be set at? What else should I be looking for to get spark to the plugs?
