On this 17.5 briggs, the starter gear seems to be hanging up in the fly wheel, a lot. If it doesn't start, (because of the compression release problem I think I'm having), when I have to turn it over by hand, I can feel the starter still engaged when I turn the key off.
Waek starter? Weak Spring? Not adjusted right (not a lot of adjustment on it). I've had this problem before on different engines. But never really addressed it.

not sure of the year of your engine, but does this have a plastic starter drive gear? teeth may be marred causing the gear to hang up
