I seem to be having a problem with my starter disengaging from the ring gear. I already had the starter replaced when it wouldn?t release when the engine started. I thought it was my starter solenoid but now I think there is another issue. Should I lubricant the ring gear? Is it perhaps too tight and I should make a shim to pull the starter a little away from the ring gear? Any suggestions appreciated. This is a RV-14A with a standard IO-390.
