Multiquip 16166ZDJ851 Main Nozzle - OEM Replacement Part for Rammers

The main nozzle is a critical carburetor component that meters the precise fuel-air mixture required for optimal engine performance in tamping rammer applications. This OEM nozzle ensures proper fuel delivery to the Honda GXR120RT-KRB6 engine, maintaining the 644-695 blows per minute and 2,653-3,080 lbf impact force specifications required for effective soil compaction.

When troubleshooting fuel delivery issues—such as engine running but rammer jumping erratically, improper operating speed, or failure to maintain governed speed of 3,800-4,100 rpm—inspect and replace the main nozzle if clogged or worn. This component works in conjunction with the fuel shut-off valve, fuel filter, and fuel lines to deliver unleaded gasoline from the 2.11 quart fuel tank to the carburetor. Contaminated fuel, air in fuel lines, or a clogged main nozzle can prevent fuel from reaching the carburetor properly, resulting in poor engine performance or failure to start.

This main nozzle is compatible with the following Multiquip rammer model:

• MT77HFR Tamping Rammer
