Just finished making a throttle shaft for a 5 ball carburetor. I used a slotting saw to make the slot in the shaft. Also used no 43 drill and 4 40 taps for the screws. I used the old shaft as a guide to drill and tap the screw holes, so I could re use the butterfly disc. It came out good and was easier than I imagined.
Nice work Richard !
Richard, you da man!
