i was wondering if anyone had one of these that wouldnt run.im needing a part for mine and the part is the gear that pops out when u pull the rope that spins the flywheel.i dont know what its called but the rope is on a pulley attached to it.it is spring loaded and when the rope turns it springs out and has teeth on it and grabs the flywheel ,its made out of white plastic and mine broke in half.or if anyone knows a place that sells them let me know thanks
