    I have a 61 lesabre with a rochester 2 jet?? I cant find any info on the carb or ID numbers for it. It seeps fuel and the floats stick every now and then so I was going to rebuild but cant find the right kit. Any help would be greatly appreciated Jim

    Its not a 2 jet. Should be a 2GC. This is a very common carburetor. Sometimes you'd find three of them on a GTO. :3gears:

    The term "2 jet" has been used many times in various literature, so probably is not "wrong". However, Rochester mostly referred to the series as the "2G" series. The model 2G would have either no choke or a manual choke; the 2GC would have an "integral" choke; and the later 2GV used a "divorced" or "remote" choke.

    Unfortunately, prior to the 1968 model year (federal smog emission); the Rochester carbs were mostly identified by tag only. Commercial rebuilders would "group" many different carburetors together, building to a common "specification" that was different than any "factory" specification. Thus the commercial rebuilder would remove the tag. While the commercial rebuilds would "work" (albeit infrequently as well as original) as a unit; internal parts are not necessarily the same, thus making kit selection difficult for these commercially rebuilt units.
