Engines built in the 1990-92 model years (Mfg. Code H2). It is built to restore carburetor performance to original specification, addressing the wear, gasket failure, and fuel-metering drift that cause rough idle, hesitation, flooding, and hard starting in aging marine carburetors. The kit is engineered for this specific carburetor application so the components are a precise fit, form, and function match rather than a generic universal kit.\u003c\/p\u003e\u003cp\u003eThis kit is the correct rebuild solution for boat owners and marine technicians servicing 4.3L GM-based engines equipped with the Holley 2300 2-barrel carburetor, and it cross-references directly to OMC and Volvo Penta OEM part numbers, making it easy to source the correct rebuild parts without hunting down a discontinued OEM kit.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Sierra\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number:\u003c\/strong\u003e 18-7238\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Carburetor Kit\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Components:\u003c\/strong\u003e Carburetor Kit\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Engine:\u003c\/strong\u003e 4.3L, 4.3L H.O.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eModel Years:\u003c\/strong\u003e 1990-92\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCarburetor Mfg.
