    That first pic, there is supposed to be an inspection sight glass for the float bowl. The other opening is a cover over it. Here is a pic.

    Re: Help with vac removal

    Let us know how that stage 4 vacuum removal runs. I was going to try it at one time, but finally got my carb to run right after hours of messing with it. I even still want to get a weber, but I'm going to hold off for a while.

    I think I read a post that says do not PM him for technical questions, post on a thread on the subject or start a thread.. I could be wrong though
    Stage four does not use any thermovalves that I remember. But....Depending on your climate you may want to consider keeping the choke set up, vacuum advance thermovalve too, for driveability issues.

    Yeah my mail box gets full, but really its so more members can read up on questions and answers, and any relevant info isn't hiding away in someones PM box where only they can see it.

    Re: Help with vac removal

    I have removed almost all of the vacuum lines including the white valves. And Just hooked up the lines shown in the stage one vacuum line removal and am now experiencing hesitation problems. Once over 4k rpm's it takes off but under that it seems gutless. And anyone know of a place to get a brass cap for the air suction tube that comes out of the exhaust manifold.

    Thank you for any help, i really need it lol

    Re: Help with vac removal

    don't worry about the AS tube.

    Did you keep your Air Jet Controller hooked up? when you remove that your carb will run rich.
    It also runs rich from removing the vacuum lines in general because you're not letting in extra air bypassing the venturis.

    Yeah i left the air jet controller hooked up. But i think its running rich atm, is there a air fuel mixture adjustment on these carbs? And my head gasket is leaking so am going to replace it this weekend.

    Re: Help with vac removal

    The air/ fuel mixture screw is on the back side, on the lower plate. It has a tab in there you have to pry out to gain access to the screw. More than likely, you will have to pull the carb off to get it out.

    when i devacs a carb i unscrewed that air mixture screw for the idle and filled it with shit. removed every other bullshit addon to the carb and installed the manual secondary flap and adjusted the idly using the throttle stop screw. worked good till we decided the car needed to be sold
