   The normal installation attaches the Flo-Commander main unit to the main air-jet/restriction passage on each carburetor body. The Flo-Commander Fuel / Air Management system will  then be functioning whenever the main fuel / air circuits are functioning in the carburetors. The main circuit just starts to work at approximately 1/8 throttle opening to WOT. The main-circuit is pretty much in full control by approx. 30% open throttle to W.O.T.

We also started supplying systems for the pilot circuits as well due to so many requests after Riders, Racers, & Engine Builders saw what it did for the main circuit!
