I am running duel model b style number 2 carbs on a stock model a ford motor . They. Are up drift . They are set up on a vortex manifold. The timing is right on . I have installed a Nu-Rex automatic spark timing system (mechanical advance) . I am running a fuel pump . The model bs have the float springs and baffles installed. The floats have been adjusted to the 5/8s height . All the linkage is set correctly. Pump pressure is one to one an half pounds( floats hold. No gas leak) my problem is it will not idle under 1000 to 800 rpms. When I adjust the gav it does not change . On b carbs this is the idle adjustment. Forgot to tell you the carbs have been rebuilt and run on a different car . Also when I come to a hard stop its some times dies. That is a float height adjustment. I have talked about this on ford barn. Thought I might get some other ideas from this site . I might have to live with it ,hope not. Miff
Miff, I split my time between HAMB and fordbarn. I have a couple of Model B's so I probably would have noticed your post there. I also have a Trojan manifold with two updrafts that I will probably run, another reason I would have noticed it. Could a person tell what was in the post by the title? Can you post a link?

Thanks for the reply.i don't know how to post link to my old posts. They were about stalling. I was asking if anyone was running the up drift carbs . On a model a ford motor . I am new to posting at h a m b . Did not know where to post Miff
Go to your old post on fordbarn. Highlight the address of the post in the bar at the top of the page. If you have a MAC press "command" and "C" at the same time to copy ("Cntl" and "C" at the same time for a PC) Come back to the HAMB site and press "Command" and "V" at the same time ("Cntl" and "V" at the same time for a PC). This will post the link into the post you are making on HAMB. If you cannot find your old post on fordbarn go to one of your current posts and click on your name. This will bring up a screen that will give you the option to "Find more posts by ...". By sure to try this as it is a technique that will be valuable to have for use in the future. Charlie Stephens
