I have the z24 with weber manual choke.
Idles perfect and revs high with no hesitation in neutral, but when I accelerate it's bogs down sound like it's choking mid pedal. If I feather lightly it accelerates slowly, if I mash the pedal it accelerates somewhat like it should I get a max speed of 75. But it takes awhile to get there. My guess from reading these forums may be a high idle speed adjustment? Is this correct or am I way off?

ever figure this out? im having similar issues bogs down at about 1/3 throttle in all gears. my idle is also high (about 1500RPM).
