Holley 4160 Carburetor Question
Ok so I have a Holley 4160, 1850-4, 600 CFM carburetor on my '63 bird. When I got the car it hadn't run in about 14 years so I figured the carb would need cleaning. After a can of carburetor cleaner I was able to get the car running pretty good but it is running really rich so I decided to clean it and put a refresh kit in it. While taking it apart, I found the secondary float was screwed all the way down so I adjusted it according to the instructions as well as the primary. I put it all back together and got it on the car and now the car hardly runs, spewing black smoke out the exhaust. If you screw the float level almost all the way down on the primary, the car idles ok but starves on throttle. The fuel/air mixture screws do not help either. I also noticed gas dripping from the venturi into the intake on the primarys which I know is part of the problem. What CFM carburetor should be on this car? Should I just go ahead and replace it with another Holley (why / why not) Is the Holley 0-1850S the same carburetor only updated?

Well I guess we have no carburetor gurus here. I replaced it anyway with a Holley 0-1850s and its running great. The 1850s has a manual choke (which I will be replacing with an electric one as the old one heat operated one was broken) and an extra transmission downshift which I won't be connecting. It fired right up without adjustment but it is running a little rich so it could probably use a little tweaking. My vacuum came up on the gauge and looks to be right even though I have a little exhaust manifold leak at #4. All in all, $250 well spent vs my time and headache on rebuilding the old one. Anyway the list is growing on a 'free bird'
Car - free Towing - $300 Battery - $80 Fuel Pump - $36 Lower Coolant hose - $20 Plugs and Wires - $45 Carburetor & gaskets - $255 Transmission Fluid - $10 Tires - $250 Brown Black Widow spiders and egg sacs - FREE (I think I killed them all though)

The car came from the factory with an Autolite 4100, which was a GOOD carburetor.
Why not use one on your car?

Two reasons:
1) I already purchased the Holley - which is easy to work on and capable of being tuned. 2) I needed it quickly and no one responded to the question.
