Back in the dim past, when I had access to a good lathe, I would sometimes make my own from stock originally bought for shear pins. This was sometimes necessary because renewing the taper shortens the needle valve which can cause the carburetor cover to interfere with the adjusting knob. I found many outboard owners resent the stops placed on the cover because it makes it harder to stop the leaks from dirty float valves by turning in the adjustment valve. . . . 😆
