Sorry about the late reply, I dont frequent this forum much.

What's the condition of your plug wires? I know that the original plug wires were made into the coil(s).

If your spark is weak, you could try removing or unscrewing your plug caps, the thing on the plug wires that goes on the spark plugs. The original plug caps were terrible at allowing the connections to the top of the plugs to corrode. Not good for electrical contact. If they dont come off, you may have to cut the wires flush with the end of the wires and find some replacement NGK plug caps. They're inexpensive and come in 4-6 different styles, just match the design to your original. Trim about 1/4" of the end of the plug wire off. Then screw the replacement plug caps back onto the wires, and try them out. If you still have weak spark, then you should look at your coil. There are aftermarket replacements that you can adapt to your machine. NGK makes some, as well as Accel. There may be more alternatives as well, but IDK, I didn't search. You can.

IIRC, and someone please correct me if I'm wrong, these were 6 volt. If your 6v battery isn't in tip top, or new condition, it's going to be very difficult to get it running if the supporting electrical wiring and connections are crappy. Check ALL of the wiring, and ALL of the ground and connectors, clean them well, and maybe put a dab of dielectric grease to avoid any moisture corrosion on the connections as well. Works the same as a 12v system too, although the 6v systems were much more temperamental.
