Multiquip 2166230308 Pilot Jet EH12-2D - OEM Replacement Part

The pilot jet controls the fuel-air mixture at idle and low throttle positions in the EH12-2D carburetor, ensuring smooth starting and consistent low-speed operation on tamping rammers. A clogged or worn pilot jet causes hard starting, rough idling, and poor throttle response during warm-up—critical symptoms that affect productivity on job sites.

This genuine Multiquip pilot jet is engineered specifically for the Robin EH12-2D 4-stroke gasoline engine, which powers these rammers at 4.0 hp with 7.38 cu.in. displacement. The EH12-2D engine uses a choke lever for cold starts and relies on precise carburetor jetting to maintain the 640-680 blows per minute needed for optimal soil compaction. When technicians experience starting difficulties or erratic idle speeds after cleaning the air filter and checking fuel quality, pilot jet replacement is the next diagnostic step.

Compatible with the following Multiquip tamping rammer models:

• MT-74F
• MT-84F
• MT74FAF
