And yes I am running two 1120 by Gary Williams on a pump gas 565 with a straub cam, its a lake boat it only turns 6200, they are 3 circuit, I run a o2 sensor and my fuel curve is perfect!!!! I idle alot in no wake zones, it out idles my single carb setup!!
I am running an 8082 on my 572...off memory thats a 2 circuit.
I think I was told it would be easier to tune than the 3 circuit deal.
Other than a pv(s) change....and a little idle adj she was good to go.
I would be curious as to what the advantage(is there is one) of the third circuit is.
