Idle adj / mid range hesitation issues Webers? (Denver)
Hi, I have a 1971 2.2 with stock P&Cs (we think
 ) and Webers. The car is in Denver (5280)Cam Unknown at this time Idle jets 55s Mains 120s Venturis 27s CO% 3.5% - 6.0% HC 6-800ppm The timing is good, valve set unknown, plugs new. The car has a heavy hesitation at mid throttle and the idle cannot be adjusted between ~700RPM (Dying) and ~1700 RPM. Does anyone have any recommendations, does this sound like a float sticking issue maybe? Any other thoughts? I have just ordered (Waynes) rebuild kits & float gauge and am planning on rebuilding the carbs this weekend. Does this seem a good place to start rather than a valve set . Thanks Sam

Hi Sam, Are you sure the venturi's are 27mm? I think they should be 30mm, and 32mm for an S model. I'm not saying that it's the problem, only that it struck me as odd. My book says a 2.2"T" or "E" model would use:
Main venturi-- 30 Main jet-- 125 air cor.-- 180 Idle--55 Emulsion tube-- F26 These are just guidelines provided by PMO
