      ok, first off I have a 1989 Honda Accord Lxi. I took it to a shop for the problem of it dying and such when I stop the car. They manually reconfigured the carb. to run on it’s own without the sylenoid. Now it runs rich when in park or neutral. When stopped normally or in gear it runs fine. Tried ajusting the throttle cable and the trottle screws. Doesn’t seem to help at all. I cannot figure out what’s going on with it.

      Thanks,
      Jay

        I really wish they hadn’t done that, those are great carbs and hold up really well over time. The most common problem with those is a leaking base gasket as it causes a vacuum leak which can cause stalling. Since your running rich you might want to check the float level by looking at the site glass on the side of the carb to see if the fuel is between the 2 marks, if it’s not you MIGHT be able to adjust it but be careful when you move the float screw it often ruins the ‘o’ ring and starts to leak. I don’t think your going to get anywhere adjusting the throttle, in fact you may make things worse.

        To be honest if you don’t understand it’s inner workings you might make things worse so that makes 2 choices for you, find someone that knows what they are doing to fix the carb or replace it with a known good one.

        BTW If it were an LXi it would be fuel injected, that’s what the ‘i’ stands for.

          [b]Ty eric, I will check it out, if it’s none of those I know a few guys I can call on if it gets too in depth.

            Wow, they removed the metering solenoid? I hope you live in a EPA test-free state..

              I think he might be referring to the shut down solinoid, there is an air bleed in the back of the carb that is controlled by a solenoid that activates when you shut the car off to keep it from running after you turn the key off. There is no ‘metering solinoid’ on those carbs, the emmissions on those systems are controled by external solinoids in the engine compartment unlike the GM version that uses the MC solenoid inside the carb.
