The metering diaphragm regulates fuel delivery from the fuel chamber to the engine, maintaining consistent air-fuel mixture under varying load and throttle conditions. When this diaphragm hardens, tears, or loses flexibility, the engine may run rough, fail to start, or surge during operation. Replacement is a standard part of carburetor rebuild service performed by small-engine technicians and experienced equipment technicians.\u003c\/p\u003e\n\u003cp\u003eThis metering diaphragm is suited for carburetor service on Poulan outdoor power equipment including chain saws and handheld power tools that use a diaphragm-type carburetor. It is typically replaced during routine carburetor rebuilds or when diagnosing fuel delivery problems such as hard starting, lean running, or engine surge.
