Hey! All this carb talk. Am I the only one around here with fuel injection? I love it. No diddling around. I don't know about any advantage to having secondaries because mine hangs in there pretty good with Bryans 385 with my two injectors. Maybe carbs can give more power, I doubt it, but the fuelly is always in tune, no matter what the weather. And a consistent 30+ mpg. It was worth the money.
