usually I just skip second gear, its a 3 speed transmission. today I was giving someone a ride on the back and it started misfiring and farting for about 20 seconds.. I had to keep slacking off the throttle for it to keep running then it just died.. I saw a little smoke coming from the flywheel area where the points are.. any ideas if that is the problem? does that sound like what happens when they go? I know more about electronic ignition.. this old stuff confuses me lol
