How many barrels does a carburetor have?
The carburetor consists of a float and venturi (or barrel). Most carbureted vehicles have between 1 and 8 barrels, and the number of barrels generally increases along with the engine displacement size. Fuel enters the carburetor through an inlet in the float bowl. The carburetor float regulates the amount of fuel that enters the engine.
How does fuel enter a carburetor?
Fuel enters the carburetor through an inlet in the float bowl. The carburetor float regulates the amount of fuel that enters the engine. It’s called a float because there is a needle that floats on the fuel in the bowl. After the accelerator pump has put enough fuel into the carburetor the needle floats upwards to seal the fuel inlet.

How to choose a carburetor?
When it comes to choosing carburetor brands, all manufacturers bring something good to the table. You just have to decide which brand will work best for you.

Aesthetics plays a big role in carburetor selection because it's important to like the way a carburetor looks when you pop the hood—especially with a show car.
What is a carburetor selection?
Carburetor selection begins with your engine's most basic dynamics, displacement, bore size, and stroke. VE (Volumetric Efficiency) is how much air/fuel we can draw into each cylinder. Piston bottom-dead-center versus piston at top-dead-center is known as swept volume—that area above the piston when it's at bottom-dead-center. You can have 350 ci with a big bore and short stroke, or you can have a small bore and long stroke. Both determine carburetor sizing and selection.
What does cam selection do to carburetor?
Cam selection has a direct effect on carburetor sizing and type. A mild street profile with a focus on torque will call for less cfm than a radical street/strip cam with 110 lobe centers and generous valve overlap. The higher an engine's peak rpm, the greater the cfm required.
How does carb spacer gain torque?
Torque is gained via the use of carb spacer. Spacer thickness depends upon hood clearance and performance. Carb spacers deliver torque because they increase velocity . The challenge is spacer thickness and how much of it you need. You can have too much spacer thickness and lose power. If you have the luxury of dyno access and the freedom of a stack of carb spacers, selection becomes easier.
How does cam profile affect carburetor selection?
Cam profile directly affects carburetor selection. Lobe centers, valve overlap, valve lift, and duration are all factors in carb selection. This leads us to cylinder heads. And this is where it gets complex because cylinder head port and chamber configuration vary even when we're working with similar castings. A set of aftermarket small-block Chevy cylinder heads versus stock iron heads determines carburetor sizing. So do the talents of a good cylinder head porter. Chamber size and compression ratio. Aluminum heads can get away with greater compression, which also affects carburetor choice.

What is a secondary carburetor?
A vacuum secondary carburetor is usually most fuel efficient when its used on street driven cars that have automatic transmissions. Vacuum secondary carburetors have one accelerator pump and work off sensing the engine load, which progressively open the secondary butterflies as rpm increases. A mechanical secondary carb uses mechanical linkage to open the secondary butterflies and most also have dual accelerator pumps (a.k.a. double pumper). Mechanical secondary carbs are best used on applications with more radical camshafts, high rpm racing situations, and manual transmissions.
What is a mechanical secondary carb?
A mechanical secondary carb uses mechanical linkage to open the secondary butterflies and most also have dual accelerator pumps (a.k.a. double pumper). Mechanical secondary carbs are best used on applications with more radical camshafts, high rpm racing situations, and manual transmissions.
What is the volumetric efficiency of a stock engine?
Any ordinary stock engine will have a volumetric efficiency of about 80%. Most rebuilt street engines with average bolt-ons have a volumetric efficiency of about 85%, while race engines can range from 95% up to 110%. Example: Using a 355 CID engine x 5,500 max rpm = 1,952,500.
