    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.

needle height

I would change the mixture screws before I changed the needles. Besides, most needles are not adjustable.
You would have to ADD shims to the current nylon spacer to lower the needle.

If you're running rich and using stock jets then something other then the needle height is wrong.

To clarify, I purchased adjustable needles and installed them during my rebuild. I currently have the clip in the third groove from the top, which almost lines up exactly with where the clip was on the stock slip. Not sure if the tapers are the same between the stock needle and the new needle though. I was getting this same bad gas mileage before doing anything with all stock stuff.

I pulled the pilot jets and checked the markings and they are stock and have not been modified (drilled out). So, I'm kinda baffled as to why the bad mileage. I pulled the carbs back off to check float heights as I ignored that before (duh). Waiting on a float height measuring tool to arrive in the mail.

Any ideas as to why it's running rich with stock stuff?

Steve, by "change the mixture screws", do you mean change the amount of turns out? They are on the engine side of the carbs, so they meter the amount of fuel rather than the amount of air. At least that's what I'm told by other members of my "G men" group. That also aligns with other things I've read. They are currently set at 1.75 turns out, which I'm also told is a bit of a lean setting already. I guess I can adjust them in maybe to 1.5 turns out and see what happens.
 
You can try dropping the needle to see what happens. If your new needle is thinner than the old the mixture will be richer than before, maybe too much so.
