My almost first one belonged to a good friend who, 50 years ago then was as old as I am now. It was from an overhead belt drive shop. He used it for steam engines. I got outbid at his auction.

I have, and use several. Largest is 12x48; smallest is 3x18. Also have the Carter prototype metering rod lathe.

Jerry - I can make carburetor jets on the 12x48, but it is MUCH easier on the 3x18.

Carl - did you sleep the night after you made the deal???

Good carburetion is fuelish hot air
The most expensive carburetor is the wrong one you attempt to modify.
