The HL 293A is a factory drilled alcohol carburetor. Manufactured by Tillotson for Hartman Engineering. He also waved his magic wand over some them and bored the venturi from 0.875" to 0.980". They are marked on back with the Hartman trademark.
The 293A has a brass high speed check valve in venturi. The HL293B is straight drilled thru the body.
Here you see the HL293A Left is stock. Right is the Hartman 980
This is the HL293B Left stock, right Hartman 980.
This is the signature logo you will see stamped on the Hartman modified carbs.
