ABSTRACT:
A carburetor fuel adjustment assembly includes a low speed needle valve and preferably a high speed needle valve threaded into respective receptacles of a carburetor body. Each receptacle defines an elongated cavity which intersects a fuel passage and has a valve orifice or seat. Each needle valve has a shank which threadably engages the respective receptacles and a tip that extends into the axially-aligned orifice or seat. The tip is axially movable relative to the orifice by rotation of the needle valve to control the size of the opening between the valve and orifice for fuel flow. A resilient body cooperates with the valve shank in laterally biasing the tip into a steadfast position relative to the orifice or seat. The lateral bias assures constant area for fuel flow through the orifice by resisting needle movement until a sufficient torque is intentionally applied to the needle valve.
