squonk 41,895 #26 Posted January 21, 2022 (edited) When rebuilding a K181 I had the EXACT same problem. Messed around for a couple of hours until I realized I needed to have both the throttle disc (part M) and the cable clamp bracket (part R1) in position on the nut.

ri702bill 8,704 #27 Posted January 22, 2022 Problem solved - I removed .065 material from the face of the nut - the assembly works as it should with the disc free to rotate and the arm held in place - shaft spins freely with about .005 front to back free play. Since I discovered numerous annoying items during the tractor's dis-assembly, I can only assume that the C shaped spacer, part R2 was originally there, lost by the PO, and was swept up with the trash and deposited into a round top trash can on wheels labeled D2. Together they made it to Hollywood - the rest is sci-fi movie history. Go back to the screen shot @squonk sent - seems there were TWO versions of the brass nut depending on the serial number. This is a late 1961 first year motor - makes you wonder ... Thanks to all for the replies. Bill Share this post Link to post Share on other sites
