I seem to have a slight issue with my QT 50. It will run fine when the switch is on start. Only problem is on start it won't let you increase the speed. Just for warming up. But once i switch it to run it cuts the motor out. If I take and flip the switch from start to run it will eventually start running and letting me use the throttle. I have checked the ignition switch and it looks fine. No broken wires or connections. I check them all through the harness wiht a meter. Could something in the CDI ignition be messing up? I have two boxes behind the seat, square black boxes. I looked in the shop manual but they don't seem to show what they are. My guess is part of the CDI system. I have yet to pull the flywheel off to check anything in there. Since it does start I'm jsut wondering what gets triggers when i change the switch to run that allows it to advance the timing and let you use the throttle. Any help would be appreciated. I'm not sure if any of you have had the same issue or not.
