    Stripped internal thread on carb float chamber

    On one of my Carbs (1980 gsx 250) , the float chamber drain bolt
    is stripped. It just turns .
    It does not leak fortunately.

    Any tips on getting this out ?
    I am ready with my cobalt and carbide drills but i know from expereince
    there is someone on here that has has the same issue.

      I would leave it alone and just source a new bowl.

          Few different ones on Ebay. Guess drain orientation isnt such an important factor as it is being reliable.

              How about grabbing the screw with vice grips and then pull while turning CCW to remove?

                  Or put it in a vice to hold it. Then use a phillips screw driver to push on it from the inside while turning it from the outside?? Or use whatever will fit against it to push with as youre unscrewing it. But its stripped already so sourcing another is in order for sure.

                          Maybe youll get lucky and the drain screw is shot and the bowl is still good. Drain screws cant be that hard to find for it.
