Throttle Return Spring Kit

The QUICKCAR RACING PRODUCTS Throttle Return Spring Kit (Model 65-096) is a carburetor-mounted throttle control component engineered for Holley 2300 square bore carburetors. This steel, chrome-plated spring assembly delivers consistent throttle blade return action, essential for maintaining predictable engine response and preventing throttle hang in high-performance marine and racing applications. The kit provides reliable mechanical feedback that experienced boaters and engine builders depend on for precise throttle control.

Designed specifically for square bore Holley 2300 carburetor installations, this return spring kit ensures smooth, repeatable throttle operation without binding or hesitation. Chrome plating protects the steel construction against corrosion in marine environments where salt air and moisture accelerate oxidation. The compact design (5.5 x 1.25 x 9.05 inches, 0.43 lbs) integrates seamlessly with carb-mounted throttle linkage systems. Proper return spring tension is critical for safety—it prevents unintended throttle creep and ensures the throttle plate closes fully when released, a non-negotiable requirement in high-rpm marine engines where throttle response directly impacts operator control.

This kit is essential for weekend fishermen and serious offshore anglers rebuilding carburetors or replacing worn throttle mechanics. High-performance racing and marine engine builders select return spring kits like this to ensure OEM-quality throttle feel in rebuilt or modified fuel systems. Whether you're restoring a classic marine engine or upgrading throttle response on a performance rig, having a reliable return spring assembly prevents costly mid-water engine behavior issues and keeps throttle control predictable under load.
