Carter YH Technical

The Carter YH carburetor was utilized on several applications, most notably on certain models of the Nash, Chevrolet Corvair, and marine applications such as the Turbo-Jet 240.

For most automotive applications with the Carter YH carburetor, the typical fuel pump pressure should be around 3.5 to 4.5 psi. However, it's essential to note that fuel pressures might vary depending on the specific application or the engine's requirements.

If you're working on a specific vehicle or engine, it would be best to consult the relevant service manual or specifications sheet to ensure you're working with the correct fuel pressure for your particular setup. Too high of a pressure can cause flooding, while too low can result in fuel starvation.
