CHANGING of the CARB – Installing PAPPY’s New Solex 1-Barrel

Working on old iron always has a way of becoming a slippery slope in that everything you do to it leads to another something that needs to be done. In the case of Pappy, our 1954 Willys CJ3B, a simple adjustment to his timing lead to me working on his points, changing out his plugs and wires and before I knew it, installing a new Solex 1-Barrel carburetor.

While the Carter YF is a good carburetor, Pappy’s was in real need of a rebuild and a few of its components were starting to become worn out enough to be a problem. While I’ll most likely still rebuild it, I decided to save that project for another day and for now, decided to just replace it with a new Solex 1-Barrel. At only $128 brand new and readily available for pick-up at my local Summit Racing, I figured it was cheap enough to give it a try and not lose any sleep if it turned out not to work out well.

On top of being affordable, a Solex carburetor is super easy to install and it’ll bolt right up just like a Carter YF. I should note however that it is necessary to lower the fuel pressure down to about 1.75-2 PSI in order for it to work properly. Typically, you can do this by installing a fuel pressure regulator but I decided to try something a bit different and that was to install a fuel pump spacer. By pushing the pump away from the block, the stroke of the pump arm is effectively reduced that and in turn lowers the pressure.
