      I think this carb had a needle valve bushing that I buggered up and drew out in pieces. I have a MD 20 parts motor with a very similar carb. I’m not sure I can get that bushing out without destroying it too. Seems to be threaded in. Anyone know the part number?

        Sorry – nothing I have goes back farther than the "H" and "T" models. That said, most of the changes between 39 & 40 were in styling. Most threaded carburetor parts had slots for a special screw driver to remove.

        . . . . . 😉

          Thanks for the reply, Gary. I’ll look to see if I can detect some slots in the donor carb I have. I wonder if one of my clever friends could make me one of those tools from your drawing?

          Did you do that drawing or source it from somewhere?

            I did the drawing.

              You’ve got skills!

              Looking at the MD 20 carb, I’m not sure there was a busing in there. I wonder if there were some aluminum washers in with the packing or something? I pulled out some sort of shrapnel, along with a wad of…. string? I’m going to try it with some more newer packing and see what happens.
