Thermoquad is a hog man. It's a big bore carb. I always did and still do like the theory behind them as well as the AVS. I messed around with several Thermoquads in the past. At one time I had about a half dozen of them had three of them on vehicles. I could never get them quite right though. There didn't seem to be good Parts availability at the time. I'm talkin early 90s mid 90s. They always fell on there face in the transition, always good off the idle and once the engine caught up it was a beast but I couldn't get the transition tuned right. The lag in the transition would have been a race loser every time. That's just my experience and I didn't have the ideal combination either so there was more than one issue causing my trouble.
