Just thinking out aloud, would it be easier to drop the gearbox instead of removing starter?

Props coming off anyway, so just bell housing bolts plus mount support (4).

The reason for mention is two fold, make sure I find this pesky shrill and 2nd, access to rounded off allen bolt for modulator.

Is it possible the TC could be touching anything, especially if bearing worn?

..ta..
