    Stuck float needle valve seat, Carb cleaning

    Hey guys,

    I'm an old hand at cleaning and dipping my carbs, but this time, I have some gunk in my gas (I don't know if it is my tank liner or bad gas). Anyway, everything is all gummy so I figured to clean everything out and dip them. Well, after 30 minutes of stripping them down, I got everything except the float needle valve seats. They are stuck. The more I try to get them out, the more I bugger up the brass. I've stopped. I figured someone here could help me out. What can I lube it with? I'm sure it's the o-ring in there, and I can't get a good grip on it. Wondering what I can fit on that small channel to help pull these out. They are stuck on all 4 carbs.

    Any help would be greatly appreciated.

    Thanks,
    Schuyler

    Hit them with a propane flame for a few seconds..after washing the bodies in some hot dish soap water to remove gas vapor and residue. Sad to tell you this, but if youve already squished the holes out of round, they will need replaced.

    I would rather trust my bike to a "QUACK" that KNOWS how to fix it rather than a book worm that THINKS HE KNOWS how to fix it.

      Chuck,

      Propane, huh?

      As for out of round, I may have buggered up the outside, but I didn't grip too hard. I knew I didn't want to do that, so I stopped.

        Yup propane torch for a few seconds to get some heat to the orings. The heat will soften the rubber and let you pull them out. few scratches on the outside isnt a concern.

        We had a member not to long ago that squeezed them and egged out the hole for the float needles..didnt "look like " too much but was enough to make the floats stick and when he replaced the seats it was healed.

            As Bill said...just enough to get then orings softened up..I would say 5 to 10 seconds tops.
