I'm sorry, but this post doesn't make any sense. You posted this in the relationship forum. The relationship forum is for questions about your relationship, problems with a girlfriend, boyfriend, wife, husband, family.

Your question doesn't seem to be about a relationship. It's also not clear enough or detailed enough to determine where it belongs.

Could you clarify what you're asking? The more info you post, the more detailed you are, the better we can help you.

Hi pizzel, you probalby have a partially stripped flywheel key.
Good luck
