This car sat for several years which was very detrimental to the K-jet system. That's my reason for wanting to do the carb swap. I've already converted the ignition to a GM-Chevy ignition module, as seen on Youtube. Works great & a fraction of the cost of original.

I've done a few B21A carbs (Stromberg) to B21/23F motors. That entails finding a donor. I did one with the mechanical pump supplied with the whole setup. The pump runs off the auxiliary shaft - provided your motor has the driving lobe (may not be there on a B230). Motors made for marine use have a mechanical pump that is available. I did one using the in-tank push pump and provided a path for the gas to the return line plumbing. I've also done a few Weber 32/36 conversions on B18/20 motors. I found those carbs to work quite well (without the noticeable loss of power with the side draft Stromberg). I prefer manual choke. I found the electric choke 32/26 comes off choke too soon in cold weather--a simple resistor (sourced from a '70s Chrysler ignition system) wired in-line worked - and then by-passing it in warmer weather. Some jet fiddling is required for individual installations. Chevy Vegas and Ford Pintos used a Holley version of the Weber 32/36 with auto choke and they provide a more normal filter housing rather than the after market foam filter you see on most Weber installations. I've given some thought to converting a B21FT intake manifold (vertical mounting of the throttle body) for use with a Weber/Holley. I have a collection of manifolds and carbs, if interested. - Dave
