Greetings!

My throttle control sticks midway through acceleration and the engine stalls. "Sticks" might be not be the right term, I literally have to push very hard to get the throttle lever to continue accelerating. Sometimes I can, most times not so much! The engine runs fine idling or at full speed (if I make it to that point). Any insight as to what might be the cause? I'd rather not have to rebuild the 3 carburetors of course... BTW, I already replaced the throttle control assembly next to the steering wheel. No change...argh. Any guidance would be greatly appreciated! Thanks.
