You may hear carburetors referred to as "one-barrell," "two-barrel," and so on, typically more barrells on larger, more powerful engines. The barrell is a tube-like part of the carburetor through which air flows and is mixed with fuel. The choke valve is at the top of the carburetor barrel and the throttle valve is at the bottom.See Also:FloodingEGRPre-ignitionPingingAir FilterExhaust ManifoldFuel PumpCombustion
