The JKTEC Model 188 is a complete engine gasket overhaul kit designed for carburetor engines, commonly used in petrol generators like the 188F / GX390 series. The pack includes a cylinder head gasket with copper ring seal, valve cover / rocker cover gasket, crankcase side cover gasket, carburetor and intake gaskets, plus two crankshaft oil seals. It is made from high-temperature resistant materials for a tight, leak-free seal that improves engine compression, ensures smooth operation, and prevents oil leakage. Marketed as high-performance, high-standard quality, it is ideal for engine rebuilds and maintenance.
