As someone who has tuned both Holley and Carter carburetors I prefer the precise nature of the AFB design for all around operation.

However if one is not familiar with the range of options in adjusting one you will get in trouble very quickly.

Just like fuel injection. If you know its ins and outs you can make wonderful things happen. Go at it like a caveman with a club and you would conclude its all junk.

The aluminum AFB body will cause fuel to evaporate at a higher rate and this is compounded by the garbage formulations they use today.

I'd rather deal with that than the Holley proclivity for excessively rich fuel mixtures to cover transitions and gasketing issues I have experienced..
