Mercurys were equipped with Autolite 4100, if a 4-barrel, or the Autolite 2100 if a 2-barrel. The Autolite 4100 is one of the finest carbs ever made. It was designed by Holley and is a square-bore carb similar to the HOlley 4150.

There is no simple answer to this question, as the Holley is a universal carb and can be tuned to suit most any application. There are how-to books on this subject, and highly recommended for someone trying to tune one. Also, the Holley tech service library can be very helpful. http://www.holley.com/TechService/Library.asp

Yes, it should. They are located on the lower front section of the carburator. These screws will only adjust the air/fuel ratio at idle. *On a holley 4160 vaccum secondary carb, the mixture screws are on the front metering block on each side. The transition slot to throttle blade relationship has to set/corrected before the mixture screws will be effective.
a double pumper is a 4 barrel carb. commonly made by holley. they were called this because they have two accelerator pumps. one on each float bowl on either end of the carb. most carbs do not have this feature, they usually only have one accelerator pump.
The 4180 Holley carb vacuum helps with transmission performance on heavy vehicles. This Holley 4180 carb is a secondary function attached to a transmission.
The simple answer to adjust the carb you have is to connect a vacuum gauge to a vacuum port on the intake manafold. Start the engine, let it warm to normal operating temp. adjust the fuel/air mixture screws. You are looking for the highest smoothest reading on the gauge. as you adjust you will want to turn the idel speed to a lower rpm. Anything further, you will need to take the carb to a pro. The smaller the carb the better the fuel mileage but performance will suffer. For a four barrel carb the smaller the primaries the better.
Yes, it's the Holley 1940. You can get them from Champion Carburetor.
sounds like a chevy motor 250 cid. you can go original which was built by rochester, believe it or not a decent parts store could hook you up. if you want a bit more power tou can look at summit racing or jegs. holley, carter, edelbrock all make something for you motor you can even by a 4 barrel intake manifold and carb for about 50 more horse power , my suggestion by a nice holley 2 barrel carb and a carb adapter
