Like it says, lost a bushing. Working on daughters JD 22hp mower. Engine is 407777-0232B1 twin. Lost the bushing on the rod from the carb to governor link. The bushing (nylon ?) is in the governor arm. Tiny little thing, maybe 1/8" od and 1/16 - 3/32" id. Can't find it on the parts diagram. Any ideas??? Thanks.............Jay
