What is a Carter BBD?
The BBD was a two-barrel carburetor manufactured by Carter during the 1960s and 1970s. The BBD was produced exclusively for Chrysler, Plymouth and Dodge vehicles. As with all carburetors, the BBD requires periodic adjustments. The idle mixture screws determine the amount of air and fuel distributed by the carburetor.
What does the main bore do in a carburetor?
Carburetors regulate the flow of air through their Main bore (Venturi), this flowing air draws in fuel and the mixture enters the engine via the intake valve. The Venturi Principle/Effect (discussed below) is critical to successful operation.
What are the 3 types of carburetors?
There are three general types of carburetors depending on the direction of flow of air.
- Types of Carburetors.
- Constant Choke Carburetor:
- Constant Vacuum Carburetor:
- Multiple Venturi Carburetor:
What do the parts of a carburetor do?
Carburetor, also spelled carburettor, device for supplying a spark-ignition engine with a mixture of fuel and air. Components of carburetors usually include a storage chamber for liquid fuel, a choke, an idling (or slow-running) jet, a main jet, a venturi-shaped air-flow restriction, and an accelerator pump.

Why are carburetors not used anymore?
Most car manufacturers stopped using carburetors in the late 1980’s because newer technology was coming out, such as the fuel injector, that proved to be more efficient. There were only a few cars that continued to have carburetors, such as the Subaru Justy, until about the early 1990’s.

What’s better 2 barrel or 4 barrel carb?
With a 2 barrel carb, you get what you get. In other words; if it is a 350 cfm carb, it’s always a 350 cfm carb. This means the 600 cfm 4 barrel will actually have better throttle response, quicker off the line power and much better low-end get-up and go compared to a 350 cfm 2 barrel.
What does SU carb stand for?
George Skinner together with brothers John and Carl formed the S.U. Carburetter Company in 1910, setting up business in a small workshop in London. The initials S.U. stand for Skinners Union.
At which stroke the fuel is injected in the CI engine?

What are the two hoses on a carburetor?
The two hoses circled in red are vent/over flow hoses. Should not have any plugs in them. They basically both route between the two carbs, hanging down. Each carb has a vacuum nipple.
What sits on top of a carburetor?
As stated it’s a circular air filter. It’s positioned there because it sits on top of the carburetor. Modern cars rarely use circular air filters, they are usually square or rectangular and are connected to the air intake system by tubes.
What goes on top of a carburetor?
At the top, there’s a valve called the choke that regulates how much air can flow in. If the choke is closed, less air flows down through the pipe and the venturi sucks in more fuel, so the engine gets a fuel-rich mixture.
