As most of you know, I'm running a tri carb set up on my 315(bored 305 engine) and need some info. I'm running progressive linkeage and it works great but here's the problem. If I floor it all 3 carbs kick in which floods the engine and makes it hesitate. When crusing about 40 and I floor it there's no hesitation because the RPM'S are up. What I would like to do is keep one carburetor with no idle circuit and replace one set up like the middle one with idle circuit and make a linkeage that would open the two carbs at idle and one at half throttle. I feel this way I would be running a true 500 cfm( the 2 barrels are 250cfm each) and when I punch it I shouldn't have the lag I did before. Does this make sense ?
