    A Special Note about Email accounts!
    DO NOT SIGN UP USING hotmail, outlook, gmx, sbcglobal, att, bellsouth or email.com. They delete our forum signup emails.

    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.

18 thousanths!

I just found out from Earl that the opening in the float bowl should be 18 thousanths of an inch. That about 1/55 of an inch.

Should I meeter the straw, or try to fix the bowls? I have seen other cv carbs with the straw plugged. I didn't know why till now, but those plugs were probably meetered.

If your wondering what the heck I'm talking about I posted earlier about drilling my choke circuit in the bowls to 5/64. OOPS!
 
Re: 18 thousanths!

I have a stainless steel bristle from a brush that I use to "ream" the choke tubes if theyre blocked. The bristle is a close fit in the tube. The bristle measured 18 thou with a micrometer. Thats not quite the same thing as saying the opening should be 18 thousandths. Its probably close, but........
