2270 with Weber 44 is running rich
50 idle. 1 1/4 screw out Had 55. Drives better, but the a/f stayed about the same 135 main 175 air Floats set at 9 with gasket Have wideband sensor 11.0 at idle Light throttle might see 12.8 Decel 13.2 Full throttle 13.7 Is there a air by pass circuit?

I have no business replying as I am rebuilding my Weber 44's now and my car has yet to run - BUT, all the research I've read says float setting is 10.5-11.5mm WITH the gasket on, set with top section held vertically on bench.
And in fully dropped position set at 32mm........ Seems to me that floats at 9 would be running rich....... But then I have no experience with Weber's yet and am just learning.....
