Description of Change: New gaskets are being used in the prechamber groups on G3600 Engines. The new gaskets provide improved resistance to corrosion. The new gaskets also provide excellent characteristics for sealing. The new 219-6908 Gasket (1) is used with all one-piece prechamber groups. This gasket is also used in the lower location with all two-piece prechamber groups. The new 219-7009 Gasket (2) is used in the upper location with all two-piece prechamber groups.
