    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.

]Do I have the O ring for float bowl drain?

I think I missed something, this o-ring (rest on the bowl in the pic) looks entirely different from anything in the set I purchased.

The one that came off seems fitted with two notches to fit into the hole.

 
I found this thread
http://www.thegsresources.com/_forum/showthread.php?t=219571&highlight=float+bowl+gasket&page=2

and this from Eil: "So to answer your question, the Rober Barr o-rings will work just fine. They squish down to fill in the cutaway in the drain bowl. You have to be careful not to over-tighten them, though, because if you do you'll mangle the o-ring and cause a leak. (Ask me how I know. :P)

I've often thought a thick rubber gasket would be a better fit for these drain bowl screws, but chances are something like that would cost a lot more than bog-standard o-rings.

Just take the bowl and screw to local hardware store plumbing section and rummage thru the buna o-rings to get a nice fit. Carb bowls don't get that hot so buna is fine and has added bonus of swelling a bit when gas hits it.
 
The o-rings in the D envelope will work just fine.

The notches in the old o-rings are there because some Bozo cranked down on the screw a bit too hard, then left them there for too many years.

Find an exploded diagram of your carbs. Odds are, the diagram will show a washer that is used as a gasket. It's a hard fiber washer. That, or a substitute, is what you're looking for. There's a similar thread on this topic with a few good substitute suggestions.
 
Put a dap of grease on all those orings including the drain plug before you install & you won't ruin any.
