The carburetor is also equipped with a high-quality, adjustable accelerator pump, which delivers fuel to the cylinders during acceleration. This ensures smooth and powerful acceleration, even under heavy load conditions. The pump is adjustable, allowing for fine-tuning to suit the specific engine and application.

The FR-4777CE is also equipped with a secondary fuel pump, which is activated during high-RPM operation. This provides additional fuel flow to the cylinders, ensuring that the engine continues to receive ample fuel even under high-load conditions.
