I see a couple of you recommended Demon carbs to the OP. Have they gotten any better?

I have used two of them and had issue with both. One was bought brand new, the other was used. The used one was literally untunable.
We may be talkin about different carburetors. I'm talking about the newer little three barrel carburetors patterned somewhat after the Thermoquad. They are great. I have on on my truck and it runs fantastic.
