When a pilot adds heat to the carburetor, it initially increases engine RPM because the heat helps to vaporize the fuel, improving the fuel-air mixture and enhancing combustion efficiency. However, as the heat continues to rise, it can lead to a richer mixture or vapor lock, causing a decrease in engine performance and RPM. Additionally, excessive heat may also negatively affect the engine's overall efficiency and lead to an increase in the likelihood of engine knocking, resulting in a drop in RPM.

Carburetor ice typically forms in conditions of high humidity and low temperatures, particularly when the temperature is between 20°F and 70°F (-6°C to 21°C). It occurs when the fuel vaporizes in the carburetor, causing a drop in temperature that leads to moisture in the air freezing. Rapid engine power changes, such as during climb or descent, can also exacerbate the formation of ice. Pilots should be vigilant for these conditions, especially in moist air or during prolonged descent.
