 Just looked at your photo and couldn't help noticing that the top covers on both of your carburetors are installed incorrectly.  See the attached photo for the correct arrangement.  Very often, when this has been done, it's a sign that whoever last rebuilt the carburetors had no idea what they were doing.  Strombergs work well when correctly assembled -- and rather poorly when they aren't.

Fixing this cover alignment problem merely requires undoing the four screws holding the cover in place, then lifting the cover up.  Inside the carb you will now see a black rubber diaphraghm bolted to an aluminum center piece (the vacuum valve).  There's a tab on the edge of this diaphragm, which must fit into the corresponding groove in the body of the carb.  At the same time, the holes in the bottom of the vacuum valve must face toward the engine side of the carb (and if that's wrong, it'll need fixing, too: unbolt the center ring, correct the misalignment and make sure the inner tab is correct, then rebolt).  Next, reinstall the cover with the correct orientation and tighten the four securing screws.  Repeat for the other carburetor.

If you don't have access to the Stromberg rebuild article printed in recent back issues of the JHPS magazine, let me know and I can send you a copy of the text.
