Just a thought from up here in Washington State, where pre-'68 cars don't
have to go thru emission testing:
If your Stromberg throttle shafts have worn elongated holes in the carb
bodies (the norm), then you're probably running leaner at idle and richer at
speed. If the idle emissions are well within the limits, you might try
leaning it way out to the point where the engine at idle still marginally
passes the test. This might lean out the carbs enough at speed to pass it
overall.
I suppose this strategy might be 'old hat' to the folks who regularly have to
go thru the test.
