Regarding the flywheel, it has been pointed out by far more knowledgeable members than me that a single cylinder engine will never have good balance, you are not likely to be able to pick up the difference even if you have one or two fins broken off which is a lot more material than the little bit scratched up by your loose bolt. If the mechanical damage affects the way the flywheel fits or aligns with the other parts underneath, I should be able to help you with a replacement.
