Chad - one way one could tell the imitations (by definition, a clone is an exact replica, so they are definitely NOT clones wink ) of the YF's used by Willys on the Jeep, was the imitation had an aluminum (or what appears to be aluminum, who knows for sure) throttle body. Carter used cast iron.

Other than quality control on the imitations, which is, at best, questionable; they are two major reasons NOT to buy the imitations:

(1) Calibration specifications
(2) Availability of parts (ever get a tank of bad gas, and have to clean your carburetor?)

Fixite7 - as to the propane conversion, if you are happy with them, then I am happy for you. Locally, even the propane companies that could buy propane at cost gave them up as too costly when compared to gasoline or diesel about 20 years ago, right after propane conversions broke nearly every school district in the area! But the engine rebuilders and machine shops were never happier!!!!!!!!!!!!!!!!!!!

EDIT: Fixite7 - nice one! You got me! I didn't realize today's date! wink

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