    A note to old forum members...
    I receive numerous requests from people who can no longer log in because their accounts were deleted. As mentioned in the forum FAQ, user accounts are deleted if you haven't logged in for the past 6 months. If you can't log in, then create a new forum account. If you don't get an error message, then check your email account for an activation message. If you get a message stating that the email address is already in use, then your account still exists so follow the instructions in the forum FAQ for resetting your password.

    Have you forgotten your password or have a new email address? Then read the forum FAQ for details on how to reset it.

    Any email requests for "can't log in anymore" problems or "lost my password" problems will be deleted. Read the forum FAQ and follow the instructions there - that's what we have one for...

  • Returning Visitors

    If you are a returning visitor who never received your confirmation email, then odds are your email provider is blockinig emails from our server. The only thing that can be done to get around this is you will have to try creating another forum account using an email address from another domain.

    If you are a returning visitor to the forum and can't log in using your old forum name and password but used to be able to then chances are your account is deleted. Purges of the databases are done regularly. You will have to create a new forum account and you should be all set.

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.
 
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. :)
 
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.)
