Horespower

• Stromberg aircraft carburetors were supplied in aircraft which had relatively high horse power. Under high-power engines, the air flow and injection of fuel becomes critical. These must be regulated to a great degree. Stromberg carburetors have the advantage that they regulate fuel very finely. Planes that run on 1,000 horsepower need exactly 437.5 pounds of fuel to produce the required energy.
  
  

Gasket

• The gasket on the Stromberg carburetor is a bit out of the ordinary. While the thickness of the gasket determines the fuel height, there is no available guidance for the height or thickness to start. Therefore, there is a process of trial and error to determine the exact right starting and stopping point for your fuel height in the carburetor for the specific aircraft.
  
  

Negative Gravity

• Stromberg carburetors had another interesting feature in that they solved the problem of negative gravity. They could continue to inject fuel into the engine at a constant rate even under conditions when the gravity was going in the opposite direction of the plane. The solution came by increasing pressure and removing the "float" which allowed the fuel to freely move around.
  
  

Metering

• While most carburetors in modern times have manual metering to allow for fuel injection to be manipulated, the Stromberg carburetor has automatic metering. It uses a vacuum of low pressure to divert air through the system to higher pressure locations. While this is simpler for the pilot, it restricts the ability to regulate the power of the aircraft as well as automatic metering.
