After several carb rebuilds, replacements, tune-ups, part replacements, and adjustments, the rebuilt 1954 chevy 235 in my 46 Chevy one ton truck still ran rich. After reading numerous posts and articles, I replaced the carb and original ignition as follows.
Carb is a 1977 factory rebuilt Rochester carb for a 250 inline chevy 6 (ebay-$46). Flange and linkage worked with minimal adjustments. Auto choke removed to permit use of manual choke. No more rich running.
Distributor is an aftermarket HEI unit with integral coil manufactured for this series engine (ebay $125). The unit bolted right up with no alterations needed. Wires were replaced.
Engine fires up instantly, runs much smoother, quieter, with improved fuel economy.
One of the simplest alterations I have performed.Don't know why I waited so long.
