Cool. I guess I'll give it a try. The newer carb also has better sealing, and a composite body to keep the fuel feed cooler, all features that I appreciate. I'm not too worried about fuel consumption, because the same car with a .18 engine runs until I get bored. If the engine turns out to be a pig at low RPM and lowering the shim stack doesn't help, I'll have my answer and I'll swap the stock carb back in.
