How does swapping in the 1470 assembly affect throttle response?

Replacing a degraded accelerator pump restores the rapid burst of fuel needed at throttle opening, reducing hesitation and improving acceleration crispness. The correct pump volume and spring tension help maintain consistent shot duration and fuel metering under varying throttle inputs.

• Restores immediate fuel delivery on throttle tip-in
• Reduces stumble and flat spots during acceleration
• Maintains consistent pump stroke and cup seal for repeatable performance
