i have just rebuilt my e93a and am getting consused with setting the timing. I know the firing order 1243. Am I right in thinking that when the timing pin is reversed and the motor is turned so the pin goes into the into the indent that the position that the rotor is pointing becomes no1 in the firing order?

Correct

As long as
number one piston is at TDC when the pin 'drops' in the indent the rotor arm is at number one.

PS. on mine in the DLM plug one is, looking forward, is to the right.
The rotor arm points to the front right hand side of the engine.

The handbook and the factory manual have good clear steps in setting up the ignition timing at the dizzy, worth looking one out if you've not got a copy.

I have found the "hit and miss" pin method near but not near enough. Whilst I have the engine on the support and the DTI/timing wheel in place, i drill two holes through the engine casing, with a little work with a file turn them into a spectacle shaped hole ie form a pointer, over the flywheel then mark the flywheel at TDC and at 20degrees advanced. This takes out any stretch in the cam chain and indicates exactly where the timing should be. I mark the 20degree mark to time with a strobe light at 3000rpm fully advanced. Works perfectly.
