A-B1843099-AI JET-MAIN

One New Aftermarket Replacement Main Jet (High Altitude) Fits Briggs & Fits Stratton Small Engines

This aftermarket replacement main jet (high altitude) Fits Briggs & Fits Stratton carburetors used in small gasoline engines powering lawn mowers, lawn tractors, and outdoor power equipment. The main jet is a precision carburetor component that meters fuel delivery at higher throttle positions, ensuring the correct air-fuel mixture for consistent engine performance. The high-altitude designation means this jet is calibrated for use at elevated elevations where standard jetting runs rich due to lower air density.

This jet is used in Nikki-style carburetors found on Fits Briggs & Fits Stratton Intek single-cylinder and V-twin engines. Compatible equipment includes Fits Briggs & Fits Stratton engines, Fits Toro lawn equipment, Fits Craftsman, and Fits Poulan powered products. Due to the very large number of compatible engine models (2,000+), verify fitment against your engine model number before ordering.
