Well Pauly,
I had problems with a ford engine/webber carb set up and it will definitely be an intake issue. I never got to the bottom of it completely but did improve it. Check all the intake vacuum areas thoroughly. Think about the old 100E with vacuum wipers.... foot hard down and the wipers stop, cruising with a light throttle and they're going ten to the dozen! So accelerating away you are loosing that vacuum at the jet/s. jetting change's can help but will effect fuel economy. what air filter system do you have? too much air or starved will have an effect. If feeling chocked on acceleration is the accelerator pump delivering to much fuel or is it starved of air or perhaps leaking vacuum somewhere. A worn needle valve can really have an effect too!
