    Fuel bowls leaking 79 gs750

    I took the carbs Into work tore them down, media blasted them, dyed them, and reassembled them. The bike had a good idle, terrible mid throttle, and would stall under wide open.So I moved the c clip on the needle in the throttle bore down a notch and and seemed to help a ton. As far as jets are it's stock jetting. Bike fired up first kick and idled well however I noticed a fuel smell and it looked a little rich out the exhaust, fuel was pouring out of the mating surface between the bowl and bottom of the carb(almost as if there was no gasket).So I phoned a friend and he suggested to adjust the floats but I'm unsure how and also confused as to why it's leaking a ton of fuel from the mating surface. Any help would be greatly appreciated

    Floats? you bend the little tab to achieve the correct height, What did you measure the float height with?

        The fuel shouldn't be anywhere near the height of the gasket no matter where the floats are set. Something isn't working right in there.

        Dyed?

          I didn't touch or measure the float height
          And if they weren't clean from being in our hot tank , no amount of berrymans will do it
          Carbs were apart at one point before so they weren't too bad Inside

                          Well, you're careening down the track of assumption, which is how the Top 10 Newbie Mistakes post came to be.

                          Do you verify the passages by squirting some carb cleaner down them?

                          Did you completely disassemble them prior to hot tanking?

                          Did you replace the O rings?

                          Did you read the carb tutorial?

                          You can't clean a carb and put it back together to the wrong spec with a clogged passage and 30 year old O rings and expect it to work right

                          Were the carbs working before?

                          Did the bike sit for a long time?
