I'd read another thread on here about a stuck start valve which was fixed by hitting it!

Start valve and starter motor are 2 different things.

Start valve is an electrically controlled pneumatic valve that opens to allow air to act on the starter motor, which spins, and is coupled to the engine gearbox by a shaft. The start valve can be manually driven to open in case of some failure in the electrical side of the valve, normally a 3/8 drive t-handle will do it.
