Here is a link to the parts catalog:Left & right Bar lock spring plastic housing, maybe someone knows the part number I attached a picture. Some times it is very hard to start and we think it is because the left lock is not disengaging..
Thanks for the help I ordered 2 of them , one was cracked so I ordered another. Do you know where I might be able to get a carburetor for the 642 with the Ford Engine?Yes, they wear out. And mine would stay "locked" on that side. I replaced both of mine on my 863f. I ordered them on-line. It was an easy switch. I think a Pin holds it on.
