B1W86523 Check Nozzle Valve Kit 86523 Fits Walbro HDB HDC SDC MDC Carburetors

One New Aftermarket Replacement Check Nozzle Valve Kit 

This check nozzle valve kit restores proper fuel delivery in Fits Walbro diaphragm-type carburetors used on chainsaws, trimmers, blowers, and other small-engine handheld equipment. A worn or failed check valve causes hard starting and erratic idle -- the engine typically runs fine at wide-open throttle but struggles at low speed. This 3-piece kit includes a check valve, diaphragm, and welch plug.
