Multiquip 1616235208 Needle 19MM - OEM Replacement Part for Rammers

This 19mm carburetor needle valve assembly regulates fuel flow in the Robin EH12 series engines that power Multiquip's MT-series tamping rammers. The needle valve controls the air-fuel mixture during engine operation, directly affecting throttle response, impact force consistency, and the rammer's ability to maintain the specified 640-680 blows per minute during soil compaction work.

In MT-74F and MT-85H rammers, proper needle valve function is critical for maintaining the specified 3,100 lb impact force and optimal travel speed of 29.5-39.4 ft/min. A worn or damaged needle valve causes rough idling, inconsistent ramming action, poor fuel economy, and difficulty maintaining engine speed under load. Replace this component if you experience hunting or surging at operating speed, inability to achieve full throttle response, or when the centrifugal clutch fails to engage smoothly as engine speed increases.

Compatible with the following Multiquip rammer models:

• MT-74F
• MT-75H
• MT-84F
• MT-85H
• MT74FAF
• MTR40SF
• MTX60SF
