Buying advice

When choosing a replacement carburetor, match the CFM rating to your engine’s displacement and intended use, verify that the throttle bore size fits your intake manifold, and consider whether you need a plug-and-play unit or one that allows extensive tuning. Budget options work well for daily drivers, while higher-flow models are better for performance builds.
