Description
Overview:
This genuine Makita carburettor (OEM 126339-4) is a direct-fit replacement for selected Makita brushcutters, including the MS4300.4U and EM4351UH. It regulates the air-fuel mixture going into the engine so the machine starts reliably, idles smoothly, and delivers consistent power under load. The assembly is built around a robust metal-alloy body with fuel‐resistant seals and diaphragms to cope with vibration, heat, and dusty working conditions. Designed specifically for the listed Makita models, it preserves the original performance, mounts correctly to the intake and throttle linkages, and connects cleanly to existing fuel lines. For regular maintenance or a worn/blocked unit, this replacement carburettor restores efficiency and helps reduce poor running, hesitation, and stalling on compatible Makita brushcutters.
