    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.

Help - pilot mixture screw

On an 850 CV carb, does the pilot mixture screw control the amount of air into the pilot circuit, or the amount of air/fuel mixture? I'm experimenting with eliminating an over-rich condition on #4 at idle and not sure which way to adjust this screw.

Thanks,
Ace.
 
It adjusts the mixture of both. My understanding is that turning the screw out richens the mixture while turning in leans.
 
Thanks Hoomgar - always appreciated.

That is consistent with name 'pilot mixture', but I didn't know for certain.

That is correct. It effectively richens the mix as you turn it out by adding a fatter mixture.

Make sure your #4 float isn't sinking and is set correctly. And eat your Wheaties.
