Increasing ethanol levels in gasoline continue to be the number one cause for performance degradation in handheld outdoor power equipment. Walbro’s Spiral Diaphragm kits make it easy for customers to rebuild their factory carburetors and eliminate future diaphragm failures caused by ethanol.
This new assembly is impervious to the effects of ethanol and does not deteriorate with age.
The Walbro Spiral Diaphragm kit has two key components: the membrane and the spiral. The membrane has a high-grade Teflon film in the center, and a Mylar carrier for handling. It has no hole and no convolution. The stainless-steel spiral provides structure and support for the membrane. When the membrane is moved by the engine vacuum, the spiral transmits this movement to open the inlet valve.
