Description
Overview:
The throttle control assembly for Honda GXH50 (GCAL) engines is a complete speed-control linkage and lever unit that transmits throttle input to the governor for smooth, accurate RPM adjustment. Built from hard‐wearing metal components with a precise linkage layout, it withstands regular use in construction and garden machinery. It restores crisp throttle response, stable idle, and reliable top‐end speed on equipment powered by the Honda GXH50, including plate compactors and small water pumps. Supplied to match Honda reference 16500 ZM7 000, it installs at the original mounting points for a straightforward swap during servicing or repairs. This assembly is suitable for routine maintenance or when the existing lever set is bent, worn, or sticking, helping to keep small engines running consistently and safely.
Key Features:
- Direct fit for Honda GXH50 (including GCAL type) using the original mounting points
- Matches Honda reference 16500 ZM7 000 for correct geometry and travel
- Durable metal construction for long service life in dusty, wet, or vibrating environments
- Smooth, precise throttle action supports stable idle and consistent governed speed
- Helps resolve sticky throttles, hunting, and poor return to idle caused by worn linkages
- Straightforward to fit with standard hand tools, minimising downtime
- Suitable for compact, handheld, and stationary machines powered by the GXH50 engine
- Cross-reference available for easy identification: 16500ZM7000
Typical Applications:
Used on construction and garden equipment driven by Honda GXH50 engines, such as plate compactors, small water pumps, light generators, augers, and concrete tools. Ideal during overhauls, when linkages are bent or corroded, or when throttle response is inconsistent. Suitable for workshops, hire fleets, and DIY maintenance where reliable engine speed control is required.
