I have an issue with my Otto kickoff. sometimes it kicks out too hard and bounce right back in the hole and other times it won't kick out hard enough to go into the lane. eventually it will give a service error and stop working. after ball search it will kick out just fine. sometimes it works just fine. Ive taken apart the mech and cleaned it, new coil sleeve, reflowed the coil connectors and everything and still no luck on fixing it. Any ideas?
