A: This spring provides consistent tension on your carburetor's adjuster needle. By maintaining constant pressure, it prevents the needle from vibrating or "fluttering" due to track conditions, ensuring your fuel mixture settings remain locked in during a race.

Q: When should I replace my carburetor adjuster needle spring?

A: You should inspect or replace this spring if you notice your carburetor settings drifting during a race, if the adjuster needle feels loose, or if the spring shows signs of fatigue or deformation. It is a low-cost maintenance item that is vital for consistent engine performance.

Q: Is this spring compatible with all Tillotson carburetors?

A: The 24B-449 is designed specifically for Tillotson carburetors that utilize this specific spring specification. Always check your carburetor's parts diagram or manual to ensure the 24B-449 is the correct replacement for your specific model.

Q: Are there any tips for installing this spring?
