When i turn the pull start paul i hear something metal grinding , when i reverse it grinds too and when i move either the chain or the fly wheel it still happens but its not the fly wheel or chain and im not sure if it will start or not i might be out of fuel or it doesnt work. anyone have any idea? I dont know what kind of bike it is but if u need pics i can strip it n take pics. i have some wid the cover on though.
