Guys that can run 3 circuits on the street with no fouling issues is amazing.

No way these out the box 3 circuits can run clean @ tip in , as soon as the throttle blades are cracked open fuel will pour in below the boosters , i'm gonna bet anyone running a 3 circuit out the box with no modifications to temporary block the intermediate tube with a tooth pick or similar & then post back hoe that little ole mod made the world of difference.




You are absolutely correct. I spent a month dialing mine in. Once I did the plugs were a nice tan brown. It was the best carb I ever owned. I restricted the transfer slots but you could probably do the same with the intermediate circuit. I also opened up the PV chanels so I didn't need as much primary jet, but this the jetting and PV sizing will depend on a lot of things (intake, cam, engine size, etc.)
