Looking for possible carb recommendations...

Thermoquads are great carburetors. They require some learning though to tune properly. When I say that, I mean up to and including removing the top of the carburetor to make changes. Some people get skeered. There's really nothing to them, but they have a lot of adjustments. Once you figure out what they all do and how they all work in conjunction, it becomes a lot easier. The problem is that not all engines will make Thermoquads act the same, so it's something that has to be learned and not taught. Anyone that knows them can show you all of the adjustments, but each engine will require something different. Moreso than a Holley or Eddy or other type Carter.
