I'll throw something else in here seeing it's a plain bearing engine. I watched someone trying to start an OS LA with an electric starter thinking that just winding it over would draw fuel up to the carb and get it running. It didn't but what it did do was seize the crankshaft into the bush from lack of oil. I managed to free the crankshaft for him but I didn't dare try to find out what the piston/liner looked like although it seemed to start and run ok afterwards.
