Inliners International Forums General Discussion Hi Performance preferred carbs for 3x1 on a 292?

IDK which is better between those 2, but there is certainly more data available for "B" installs.
That manifold comes with progressive linkage: idles on the center only to part throttle (cruising), then both end carbs open together, with all 3 reaching WOT simultaneously.
You should reach your cruising speed on only the center, which will vary depending on gearing, etc. Many linkages have some adjustment w/r/t proportions.
Gas mileage may be worse than stock because mixture distribution is not great (center carb is right on the #3-4 intake port), and varies with throttle position. Has anyone done any mods to the plenum floor to help (ditches, popsicle sticks, dams)?
Don't use small air cleaners, no matter how good they look!
