I don't remember which brand is which but, one major brand of vacuum pump has canted vanes and the case is marked with direction of rotation. It can be damaged with reverse rotation. The other brand has straight vanes and is unmarked; you may turn it either way.
If your coupe has a Marvel carb, you should be stopping the engine with the mixture control. Leaving the mixture at idle cutoff plus having the mags off provides redundancy against an accidental start.
