Multiquip 16011ZDJ851 Valve Set Float - OEM Replacement Part

The float valve set controls fuel flow into the carburetor bowl on Honda GXR120RT-KRB6 engines, automatically regulating fuel levels to ensure proper engine operation and prevent flooding or fuel starvation. This component is critical for maintaining consistent engine performance on tamping rammer applications where the equipment operates at continuous high RPM under demanding compaction loads.

The MT77HFR rammer requires the engine to maintain 3,800-4,100 rpm at maximum governed speed with no load, delivering 3.6 hp to drive the centrifugal clutch and generate 644-695 blows per minute with impact forces ranging from 2,653-3,080 lbf. Float valve failure can cause erratic operation, engine speed fluctuations, or complete shutdown during critical compaction work. If your rammer exhibits irregular jumping, inconsistent performance when the throttle lever is properly set, or difficulty maintaining operating RPM, a faulty float valve assembly may be the cause.

Compatible with the following Multiquip models:

• MT77HFR Tamping Rammer
