Buying advice

When choosing a carburetor or fuel injection mounting gasket, consider the material (composite, phenolic, graphite) based on operating temperature and surface condition. For high-heat or forced induction, phenolic insulators or multi-layer steel gaskets prevent vapor lock and blowout. Check carburetor flange type (square bore, spread bore, TBI pattern) to ensure fit. A little extra spent on quality gaskets prevents vacuum leaks and improves idle consistency.
