I am a new member here, but would like help with my "new" 1957 Ford Fairlane (292??/Fordomatic/B intake).  My car has a Holley 4160 carb (1850-3' 600 cfm) and I would like to know what primary jet I should be running.  The carb seems to be running really rich (tailpipes black; plugs black).  According to my 1957 Ford Car & Thunderbird Show Manual the stock 4150 carb had 55 primary jets, 48 secondary jets, and a 6.5 power valve.  Any information would be appreciated.
