Moose Racing Carburetor Rebuild Kit – Honda TRX300 / TRX300FW 1988‑1990

OVERVIEW

This Moose Racing carburetor rebuild kit restores precise fuel metering and stabilizes engine operation for vintage off-road machines. Designed as a comprehensive solution for Honda ATVs, the kit replaces worn gaskets, O-rings, jets, and the float valve to return the stock carburetor to factory-level performance. Riders receive every critical internal component required for a complete overhaul, ensuring reliable fitment and long-term durability on affected models.

ENGINEERING & PERFORMANCE

Precision-machined jets and new float valves regulate fuel delivery during low-speed cruising and wide-open throttle, preventing lean surges and keeping the air-fuel mixture consistent under stress. Seals and gaskets are manufactured to match original equipment tolerances, which eliminates external leaks and maintains proper chamber pressure across varying operating temperatures. The included hardware withstands extended use under normal riding loads and preserves responsive throttle control, ensuring the carburetor performs reliably through repeated service intervals.
