Throttle Lever Bushing & Grommet Kit

The Throttle Lever Bushing & Grommet Kit by Quick Fuel Technology is a precision replacement component engineered for carburetor linkage systems that demand reliability and smooth operation. This two-piece kit addresses wear and play in throttle actuation, a common problem in both street and performance carburetors where mechanical linkage connects your throttle pedal to the fuel metering circuits. Whether you're rebuilding a classic carburetor, restoring a vintage engine, or maintaining a performance setup, worn bushings degrade throttle response and create dead zones in pedal travel—problems this kit directly solves.

This kit features 1/2-inch mounting diameter nylon bushings finished in black and white, materials chosen for their wear resistance and chemical compatibility with fuel and engine oils. Nylon construction eliminates metal-to-metal contact that causes squeaking and accelerates deterioration, while the tight dimensional tolerance (2.95 x 1.1 x 4.1 inches overall) ensures a snug fit in standard carburetor lever mounts. The grommet design isolates vibration and reduces friction, allowing the throttle lever to pivot freely without lateral play or binding—critical for precise fuel delivery control and consistent idle quality across all engine speeds.

Mechanics and engine builders install this kit when performing full carburetor overhauls or addressing throttle hesitation and erratic idle symptoms in Quick Fuel carburetors and compatible linkage assemblies. The lightweight design (0.03 lbs) adds zero parasitic weight while delivering years of dependable operation. Installation takes minutes with basic hand tools—no special equipment required—making this an economical way to restore throttle crisp and eliminate play before it damages fuel metering needles or creates cold-start difficulties.
