About this product
OVERVIEW
This complete carburetor rebuild kit restores precise fuel metering, stabilizes idle performance, and seals persistent leak paths to return stock engine operation. Designed specifically for the Polaris RZR 170 4x2, the assembly utilizes corrosion-resistant brass jets and ethanol-tolerant rubber-top float valves. Each metric component is manufactured in Japan to deliver reliable cold starts and extended service life.
ENGINEERING & PERFORMANCE
Precision-bored main and pilot jets maintain steady fuel flow across wide-open throttle and low-speed cruising, eliminating hesitation and flat spots. High-grade rubber float valves mated to plated metal seats block vapor permeation and resist chemical breakdown from modern ethanol blends. Model-specific jet calibration paired with comprehensive chamber gaskets maintains exact OEM clearances, which stabilizes the pilot circuit and prevents fuel overflow during transport or tight turns.

WHY RIDERS CHOOSE THIS
Operators select this kit because it addresses the exact failure points that cause rough idle and sluggish throttle rollout in small-engine UTVs. The bundled adjustment screws and calibrated needles allow quick re-synchronization of the venturi passage without trial-and-error part hunting. Ethanol-resistant sealing compounds keep the float bowl dry during storage cycles, while hardened brass jets maintain consistent spray patterns under vibration-heavy trail conditions. This focused component set restores factory throttle authority and simplifies off-season maintenance for daily trail use.
