  1. Will the seat installation tool that you made fit the inlet seat on a Walbro LMK carburetor using Kohler rebuild kit 12 521 03. This Kohler kit seems to be the only way to get an inlet seat for these carburetors

  2. Cut a groove in the jet with a dremel cut off tool and use screwdriver.

    Drive the seat back in with a bolt with a nut screwed in it. Tap the seat down, with bolt in the seat and nut preventing the bolt from damaging seat.

    AND….the sleeve (bushing in your case) is the hardest part. People can't grind and cut metal in their garages. The bushing/sleeve is the whole trick, isn't it?
