found my knocking noise i took the pan off of it a rotated the crank by hand
the piston wrist pin was moving inside the rod so i pulled the piston and my rod was bad it was a factory 10hp kohler brand part i never thought to check it because i never even looked at the rod i just wrapped it up with the crank and sent it off the get a bearing made for it. now i have to send this other rod off

should have paid more attention to my parts i guess
