Runs fine up to 1/4 throttle and idles well

Further acceleration does nothing although the carb control levers are moving on both carbs.
Interestingly, when carb cleaner sprayed in 1st (upper) carb it tries to stall motor, when sprayed in second (lower) carb, no change.

Why won't this motor accelerate? Thanks!
