WT176-64 Rubber Check Valve for Carburetor

The carburetor of small garden machinery has a precise structure. The internal check valve is a key part to stabilize fuel supply. Constant contact with fuel will gradually age the rubber component and damage its sealing effect. If the check valve fails to control fuel flow and causes backflow, the machine will suffer hard starting, rough idle and intermittent power.

The WT176-64 rubber check valve is designed for WT series carburetors. Made of fuel-resistant rubber, it features strong anti-swelling ability and keeps fine elasticity under gasoline environment. The rubber structure realizes one-way conduction to block backflow, stabilize oil pressure inside carburetor and maintain normal fuel-air ratio for smooth ignition and operation.

This compact part is a common wearable component for carburetor repair. You can replace it easily when disassembling the carburetor without special tools. Installing a new check valve solves faults caused by fuel backflow and recovers starting ability and power output. It is essential spare part for repairing 2-stroke machines such as chainsaws and lawn trimmers.
