i was able 2 remove the old flywheel (magneto) but now i want 2 put the new one on and i cant get the key out, it is stuck in the crankshaft, there is no room to even apply any pressure to it, how do you get these things out? I AM SO IRRITATED! been working on it for 3 hours now, no luck, i dont want to damage it cause i dont have another 2 replace it, and i dont want 2 damage the shaft either this job seems impossible.please help
