I doubt both carbs would have the exact same problem- be it float level or whatever. But a too-high level could slosh fuel into the carb through the vent(s), unregulated. This will cause a bog/stutter/stall. The float level is easily checked, so I would pull the sight plugs and take a look, just to be sure.
Also fuel related- be sure the accelerator pump arm is in contact w/the linkage so there's movement of the pump diaphragm the instant the throttle is moved. Just be sure there's 0.015" clearance between the arm and linkage at WOT.
But if it's fuel related, I'd be rather surprised. I'm thinking electrical/ignition related. Chaffed wire, something rubbing, that sort of thing.
