    Gas coming out of right carb of 79 GS425L

    So I had my carbs rebuilt, and I've ridden the bike a few times since and i've had no problems. This morning i went out, started the bike and gas started coming out of the overflow tube on the right carb (not dripping, but more of a steady stream). I tried tapping the side of the carb a few times, thinking it might be dirt under the seat. That didn't work.
    Do I have to take the whole carb apart to fix this problem, or is there any other alternatives that might help me fix this problem.
    PS - I'm an idiot when it comes to carbs, and don't know much about them.

    Thanks

    Obviously, the float is sticking. Could be: worn needle/seat, float is not floating, seat seal leaking, float too high, foreign material such as rust keeping needle from seating. If there is foreign material blocking the needle you might want to check the tank to make sure there isn't any rust causing the problem.

      I think I found the problem.
      The float had a small pin hole leak in one side and was almost completely full of gas.
      I'll order a new one tomorrow from the dealer. Hopefully this will fix the problem.

      Thanks for the help

        I assume it is a brass float, You can sometime put a dab of solder on the hole to fix it IF you are carefull

          Yes, it is a brass float and it looks like it was put together using solder.
          Someone else mentioned that I could try doing that also. I'm pretty good with soldering electronics, and thought about maybe trying this one. If I do attempt, is there any precautions i should be taking considering these things have had gas on/in it? Can i use a soldering iron, or would i need to use a torch?

            I struggled for awhile with a similar problem till my neighbor finally noticed I had a hairline crack running the length of the overflow tube. I rinsed the bowl in water a few times, blew it out with air and soldered the crack in the tube. That was about 6 months ago and alls well though I picked up a replacement for when the day comes....Don't forget to clean the brass to get a good solder joint.

              I'm not sure but I don't think a soldering iron is going to get hot enough. Also, I think you should use the type of solder for plumbing, not electrical work. One of those mini torches would be ideal I would think. A dab of JB Weld would work as well after you hit the area with a scotchbrite pad to clean the metal.

              Good luck.

                Got some scotchbrite and polished the float up. Turns out i discovered a multitude of pinholes in the one side of the float. I attempted soldering, but it's def. not going to work. They're all over the place.
                I guess i'll just have to wait until this Wednesday for a new float to come in.
