What level should the floats be set at on a Barry Grant carburetor?
When assembling a carburetor or reinstalling the fuel bowls, adjust the float approximately .450" from the top of the bowl (in line with the bowl screw bosses when the bowl is inverted). This dry setting is to get you in the ball park. Recheck the float level with the engine running and the sight plugs out. Fuel should just wet the outside of the bowl as the fuel seeps out. On the secondary side, where the sight plug is lower, fuel level should be slightly higher.
