Good Morning all, looking to see if anyone out there would have any idea as to if there is a spring mechanism in the trigger assembly on my engine. When I remove the throttle cable from the motor, the spark advance lever will not return to it's vertical position, it seems I've lost a spring that would do that but don't know if there even is a spring in the trigger assembly or another location that might do this. Any insight would be greatly appreciated. As a temporary fix I put an external spring between the front of the engine and the spark advance lever and it seems to work for now but would like to fix it properly.
