replace it with a edelbrock, I just got a quadra jet rebuilt put it on and as soon as the fuel started flowing it was spitting gas out the top, took it off , took it back to the rebuilders had them check it out, they told me it was junk and that you can only rebuild a quadra jet 4 or 5 times and keep it functional, I let them have it and went and bought a 1406 edelbrock.
