Re: 4GC Rochester Carb for 1955

G'day all, fascinating what you learn on this site. I've just reset the float level and drop to factory spec's on the Rochester 4GC on my '56 Patrician, and wondered about how accurate my settings were. Reading about the two screws on the side of the carby that could be removed for inspection purposes gave me the advice I thought I needed. Unfortunately, the '56 4GC doesn't come equipped with these screws, or mine doesn't anyway. I wonder why Packard dropped this useful analytical component (???). Also, before the rebuild my carby was leaking and I suspect it was a combination of a very worn accelerator pump and too high a float level on the secondaries. Regards, John
