A starter is $150 and silly simple to replace. Buy a new one.

The starter on my O-360 is not releasing when I let go of the starter
button. If I rev the engine slightly, it disengages at about 1500 RPM's. I
have sprayed silicone spray on the ring gear, and well as the bendix of the
starter but have only started it once since and it still stuck. Is this
common? Is there a common fix? Has anyone had one apart? I'd like to know if
the engine spinning faster causes it to disengage, or if it's only a a
spring loaded bendix alone. Any help would be appreciated.
