Had much the same problem with Thermoquads on big blocks a long time ago. The bottom plate on these warped, possibly from overtightening the mounting bolts. Also had re-occuring problems with the base gaskets - not sealing after installation. One possible check to make - fill a pump style oil can with gas, idle the engine and squirt gas around the base of the carb. If the engine speeds up, you've got a vacuum leak under the carb. Other than that, sounds like the engine may be starving for gas under acceleration - possibly a leaking check valve (intermitant) in the accelerator circuit.
