Description

Tillotson 24B-131 Idle Speed Screw Spring


The 24B-131 Tillotson Idle Speed Screw Spring provides essential tension to the idle speed screw, securely holding it against the carburetor body. This tension ensures the idle screw maintains its position, allowing precise control over your engine’s idle speed and RPM.


Designed specifically for a wide range of Tillotson HL model carburetors, this spring presses against the screw that engages the throttle shaft bracket, which in turn opens or closes the throttle butterfly. Proper tension prevents unwanted movement or loosening of the idle screw, ensuring consistent idle settings and smooth engine operation.


For optimal engine performance, regularly inspect your Tillotson idle speed screw spring for signs of wear, corrosion, or loss of tension. A weakened spring can allow the idle screw to shift, causing fluctuations in engine idle speed or unstable RPMs.
