You can't run that engine on 91 typically, as your country advertises gas by Research Octane # not Motor Octane #, and 91 ROI is not good enough for a 10.0 compression engine. Simply put, your 91 is like our 87. You should always be running that at the best grade available: 95 or 98 Octane.
It's good that your oil pressure is OK but you still could have problems with the oil quality. But I'm more worried about the gas.
I would drain the gas tank and refill it with 98 Octane. I'm not really sure what you mean by the "sewing machine" sound but it could be pinging. Again with that mechanic... he should have instantly been able to recognize either engine pinging or noisy tappets. Point is, before doing anything else I would replace the gas with fresh high octane gas. Then see what happens.
It can be drained into a Jerry can with a siphon pump through the filler neck. There is a drain plug on the tank but they all are rusted by now.
For the starter pinion gear, were you not able to drive above, say, 15MPH? If you were driving at normal speed, I don't see how those could be related. Well, maybe, if you literally had the throttle all the way down just to drive at 40MPH due to that issue. Regardless, your new mechanic should be able to check if your starter has issues or is damaged.
