Pilot Jet (Slow Speed Jet)
The pilot jet controls fuel delivery during low-to-mid throttle operation. Over time, fuel varnish narrows the internal diameter of this jet, creating a lean air-fuel mixture that forces the mechanical governor to hunt for stability. Replacing this granular component restores the correct fuel flow and stops the RPM oscillation.

Carburetor Insulator Gasket
An air leak behind the carburetor allows 'unmetered air' to enter the combustion chamber, bypassing the venturi. This leans out the mixture significantly, causing the engine to surge as it struggles to maintain combustion. Replacing the gasket ensures a vacuum-tight seal between the intake port and the carburetor body.

Carburetor Assembly
In cases where internal galleries are permanently restricted by corrosion or sediment that cannot be removed via ultrasonic cleaning, a full assembly replacement is the only reliable engineering solution. This ensures all internal circuits (pilot, main, and transition) are functioning within OEM specifications.
