- Genuine Husqvarna OEM Part — sourced directly from Husqvarna's construction equipment parts program, meeting the same material and dimensional standards as the original production component.
A jet is a precisely bored metering orifice inside the carburetor that controls the volume of fuel entering the engine at a given throttle position. The accuracy of the bore diameter directly determines the air-fuel mixture, which in turn affects engine power, temperature, and fuel efficiency. When a jet becomes clogged, worn, or is replaced with an incorrectly sized substitute, the engine may run lean or rich — leading to rough idling, power loss, overheating, or difficulty sustaining consistent blade speed through a cut.
