Newby here. My 84 year young neighbor was given a rusty Columbia. He likes to refinish things so he took it all apart and is cleaning and painting. He gave me the motor and coil to see if I could get it running. I like to tinker with motors but this is all new to me. With the multimeter set at 20k, the coil has continuity between the two spades, and there is continuity between either spade and the plug wire - around 16.03. . I bought a new plug. I lightly sanded the points. Everything is very clean inside the flywheel from what I can see but I have not taken it off. The motor turns freely. I squirted some oil into the cylinder to keep is lubed while testing. I have been spinning the motor with a drill. My easy question: is it possible to get a spark from the plug with the motor out of the frame? I set the plug against the cylinder fins for ground and have tried every combination of running wires from the stator, but no spark in the plug. There are two sets of wires coming from the stator. One has a blue wire and a yellow wire, and the other has a green, green/black, and a gray wire. From all I have read, the blue wire should be the wire to excite the coil. In my thinking, the blue wire should go to one of the spades on the coil and then ground the coil with the motor with a second wire, since it is off the frame, but no spark with this arrangement. Thanks in advance for educating me!
