Ive checked all electrical with the volt meter, new plugs, wire, coil, flasher, breakers, relay, good battery. Turns over and has compresion. When i check it with a spark tester,i,get no glow. Does a generator effect spark? I checked the brushes and those seem to be good. Im at a loss. Any advice?

 

Generator does not affect spark. Is your spark tester any good?

 

handelbar on-off switch

 

When i have the spark tester hooked up and i flick the off/run switch i get a quick blink of a glow. I replace the switch and it was doing the same thing.

 

Does it have a sensor or old-fashioned points? Anyhow, seems like they are not working.
