Frequently Asked Questions

Q: Why is the 37-gram tension rating important for my carburetor?

A: The 37g tension is critical for maintaining the correct "pop-off" pressure. If the spring tension is too light, the needle may unseat prematurely, causing flooding; if it is too heavy, the engine may starve for fuel at high RPMs. This OEM spring ensures your fuel metering remains consistent with factory specifications.

Q: How do I know if my fulcrum arm spring needs to be replaced?

A: If you notice sluggish throttle response, inconsistent fuel delivery, or if the engine struggles to maintain a steady power band, the spring may have lost its tension due to fatigue. Replacing it with a fresh 24B-299 spring is a cost-effective way to restore crisp throttle recovery.

Q: Is this spring compatible with all Tillotson carburetors?

A: This spring is designed for specific Tillotson models that utilize this tension rating. It is highly recommended to check your carburetor’s service manual or verify the part number against your existing internal components to ensure proper fitment and fuel pressure calibration.

Q: Do I need to adjust anything else when installing a new fulcrum spring?

A: Yes, whenever you change the fulcrum spring, you should verify the fulcrum arm height. The arm must be set to the manufacturer's recommended height relative to the carburetor body to ensure the inlet needle seats correctly and the pop-off pressure is accurate.
