For general interest - though this does not apply to the ZG62, only to the ZG20.
On the ZG20, on the carburettor side of the crankcase, there are two threaded holes that can provide an alternative mounting for the ignition sensor. With the sensor mounted in this posdition the ignition point is moved 90 degrees and allows the engine to run in the reverse direction. Being a side-induction engine it is symmetrical with regard to breathing. I have tried this and the engine ran in the reverse rotation, i.e. clockwise as seen from in front just the same as in the normal set-up. The checked rpm were the same, starting and throttling were no different.
Unfortunately none of the larger engines offers this feature.
