    I have a 2 original smogable rochester carbs circa 1980 or so. they both leak very bad. I am forced to use my 750cfm holley, unfortunataly this is not a smogable option in the good state of california. I need recomendation on where to have one of these rebuilt or where i can buy a new one(cheap)

    Thanks

    Leak? Where from? If its the carb inlet, believe there are some repair options for that, maybe even at a chain auto store. If it's leaky gaskets, $15 "rebuild" kit and an hour or so and you should be back in business.

    If they are leaking from the two small plugs on the bottom near the throttle plates, JB Weld them...worked on my old '82.

    I think Checker has actual Rochester carbs for 2 bills or so...

    My old Rochester leaked like really bad too. After I threw it away (no smog /forums/images/graemlins/laugh.gif ), I realized that my new mechanical fuel pump was creating too much pressure and made my new Edelbrock carb flood too. Apparently neither carbs' float bowls could stop the pressure from the mechanical fuel pump.

    Hence, I added a fuel pressure regulator - the cheap in-line kind, IIRC $9.98. It was chrome, has a big dial on it and reads from 6 to 1 in one pound increments. I left it on 6 on the street and brought it down to 2 when I went off-road.

    Good luck.
