RC Airplane Maintenance – Carburetor Basics
The carburetor is the part of the engine where fuel is mixed with air before it enters the engine case. The air passes though the opening at the top of the carburetor and enters the venturi, a long tapered tube that speeds up the airflow into the engine. The increase in air velocity causes a drop in pressure, which draws the fuel from the tank. In the middle of the venturi (at the low-pressure zone) is a brass tube assembly called the spray bar. The fuel passes through the spray-bar jet and then mixes with the incoming air.
The air portion of the air/fuel mixture is regulated by the large aluminum barrel that rotates to increase and decrease the size of the intake hole. The flow of fuel is adjusted by one or two needle valves at one or both ends of the spray bar.
Older 2-stroke engines (and many 4-strokes) have a single high-end needle valve to adjust the mixture at full throttle and a small air-bleed hole in the front of the carburetor to adjust the idle mixture. As the throttle barrel closes, it opens the air-bleed hole to the venturi. A small idle-mixture screw meters the amount of air entering the carburetor. Opening the air-bleed hole lets more air in and leans the idle mixture, and closing it lets less air in to richen the mixture.
Two-needle carburetors (as the name implies) are equipped with two needle valves, one for the high-end mixture adjustment, and a secondary low-end needle valve (sometimes referred to as the low-speed needle) to adjust the idle mixture. When you turn the high-end needle clockwise (screwing it in), it leans the mixture by restricting the amount of fuel that enters the carburetor. Turning it counterclockwise (unscrewing it) richens the mixture by allowing more fuel to flow. Usually, the low-end needle is smaller than the high-end needle, and in some cases, you'll need a fine-tip screwdriver to adjust the idle mixture because it is recessed into the center of the throttle arm. When you turn the low-end needle clockwise, it richens the idle mixture, and turning it counterclockwise makes the mixture lean.
When the throttle barrel is closed, it also moves laterally, which in turn moves the low-end needle gradually into the fixed spray bar, thus leaning the idle mixture. Of the two types of carburetor, the two-needle type is more sensitive to adjustments and provides faster throttle response through the midrange.
