Multiquip 1616244008 Nozzle Main EC12D - OEM Replacement Part

The main nozzle controls fuel delivery and mixture in the EC12-G Robin engine powering Multiquip MT-series tamping rammers. This carburetor component meters fuel flow to maintain proper engine speed and power output needed for the centrifugal clutch engagement that drives the rammer's compaction action. A worn or clogged main nozzle causes poor throttle response, difficulty maintaining full operating speed, or failure to achieve the specified 690 blows per minute impact rate.

The EC12-G is an air-cooled 2-stroke gasoline engine with 114cc displacement and 4.5 hp maximum output at 4,000 rpm. Proper carburetor function is critical for these rammers, which must quickly transition from idle to full throttle to engage the automatic centrifugal clutch without clutch or spring damage. A failing main nozzle often presents as hunting at operating speed, black exhaust smoke, or inability to maintain the 2,865 lbs. impact force specification.

Compatible with the following Multiquip tamping rammer models:

• MT-75H
• MT-85H
• MT75HS
• MT85HS
