I was just curious after reading the dual carb post. (saving pictures)

On, say the KB...how does the linkage work? Does it use both primaries at the same time and both secondaries when you punch it? Like you would just use less pedal because twice the gas is flowing...do you have to maybe tune down the pair (lower settings on idle mix) than you do for a single carb?

Progressive (carb1 primary-secondary, carb2 primary-secondary)from one to the next?

It seems to be two identical carbs and I probably have enough around to make one more good one, and know someone who could build an intake if some day I wanted to try that.

It's two identical carbs, both primaries open at the same time, then both secondaries open as your foot approaches the floor.

 

They're just like the single carb though if I remember correctly the true Sprinter dualcarbs have slightly smaller jets.

two carbs both the same.

Operate like a single.

Jets were smaller in twins.

The dual carb sprinter also had smaller venturi's

To work out how much juice you'll use, work out the cfm per rpm. At the ratio of 1:14.7 you can estimate your fuel consumption no matter what your induction set up.
