I have a 1942 3/4 ton using a 1962 235, with Offy dual carb intake and Fenton headers. It sits in front of a T5, and a modifed OE rear end (now 3.90). I'm having a hell of a time with the dual Carter YF carbs. One runs OK, and the engine idles OK, but the other is popping and sputtering any time it's put under a load. I went through it today and found an issue that I corrected (missing check ball in the pump circuit). That did not correct the problem. Even when these YFs are set up pretty well, they never seem to hold that for very long.

I'd like to ask if anyone has a recomendation for a better choice of carburetors for this dual carb application? I have not been a big fan of the Rochesters that were OE for the 1962 235, and from what I've read, they would dump too much fuel in a dual carb arrangement. Right now I am minimizing my use of the truck for fear of a fire.

There must be a more modern, reliable and smoother running carburetor out there, that I can buy and use as a pair. Either that or, I would appreciate your thoughts about adapting a TBI system to this Offy dual intake or, to a stock intake manifold. I suspect FI would be an improvement but have no experience with FI on these older I6 motors. Any advice or experience with the dual carb setup would be appreciated. Thanks.
