    Fuel inlet needle valve seat.



    I'm guessing you don't have to worry about scarring up the outer perimeter of this assembly since nothing rides there. Is this correct? I'm having a terrible time getting mine to come out and may have to get a good grip with locking plyers. I'm also going to put it in the ultrasonic a while to hopefully loosen it a little bit. Edit. I tried to add a pic but botched it. I will try to copy the pic on the CV carb cleaning tutorial from BikeCliff's.

    I find working on my motorcycle mildly therapeutic when I'm not cursing.

    A few marks shouldn't hurt it but of course, if you squeeze it, it could "oval"....the seat is supposed to just pull out -just an o-ring supplying friction once the "keeper" is removed. I'd try penetrating oil or atf alone (automatic transmission fluid ) a bit longer with some local gentle heating ...

    Why are you taking it out? does the needle and/or seat leak? Worn? Scratched? If something like this has no symptoms and doesn't come out easily, I tend to not "fix" it...or put it off to some future day when it's really required....

      They are always tough to get out... especially with old hard O rings. I usually end up using locking pliers too. Make sure you don't squash them. Twisting & pulling works better than just yanking. If you mark the brass that won't be a problem.

        Some heat may help. Just not too hot.

          Thanks for all the help. I'll let it soak with some penetrating oil but I think I'll probably end up going with the "If it ain't broke, leave it alone" approach. I'm cleaning the carbs for a guy who is buying my GL and have o-rings from Robt Barr on the way. I guess that's the only o-ring I won't be replacing (on all 4 carbs.)
