PWK Carburetor Jet: The "Fuel Flow Regulator" for Carburetors

For PWK-series carburetors, the precision of the jet directly determines the fuel-air mixture ratio, which in turn affects engine power and fuel consumption—and the PWK carburetor jet is the "fuel flow regulator" for carburetors.

Made of brass, this jet has two key advantages: first, brass is highly corrosion-resistant, so it won’t rust or deform after long-term fuel exposure, maintaining the precision of the internal bore; second, brass allows high machining precision—the calibrated internal bore stably controls fuel output, creating the optimal fuel-air mixture ratio.

Installation is simple: thread it directly into the corresponding carburetor port, fitting all PWK-series carburetors. Different jet sizes also meet various tuning needs—for example, using a larger bore jet for high-load operation to increase fuel supply, or a smaller bore jet for daily use to improve fuel efficiency. Whether for carburetor fault replacement or engine performance tuning, the PWK carburetor jet enables more efficient fuel atomizatThe PWK carburetor jet (brass) is a precision fuel control component for PWK carburetors, offering corrosion resistance, calibrated flow, and easy installation.
