    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 am using this to rebuild my carbs.

Everything went well and I am in the process of rebuilding. My question concerns the Idle Needle Jet. When removing the were pretty hard to remove and required some effort to get out. When reinstalling it appears that they sit in the hole and do not need to be forced into the hole. I just want to make sure that I do not need to apply undo pressure to get the idle needle the hole.

Just trying to make sure I am not insane..

Yep, just an interference fit. Put new O ring on, push in hole until they're seated properly, and done. Doing this without the gasket in place would be better...

That ridge above the O ring there should sit flush on the surface.
 
Cool thanks.. I think I am good then.. I notice that if I push the floats up they sometimes stick now. Perhaps I need to align the idle needle jet better. How much will the floats move during normal operation. I am speaking of the floats as the part that inserts into the needle jet. If I move them upwards to the top of the opening it apears they stick a bit as the idel needle jet is not perfectly aligned. If the floats never move this much then all is ok, If I need full range then I will need to play with it to get adjusted correctly. Since the idle needle jet sits in the float I had to install floats and everything and then seat float bowel so that the idle needle jet would stay in place. I think that explains it well but I can post pics if needed for further clarification.
 
Hmmmm ok I'm a little confused...

Basically the floats will only move up enough to stop the fuel flow coming in via the needle valve... at least I think my terminology there is correct.
