Daul single throat 34s ?, vacuum advance, runninig rich Options

[Hine62]

I've just installed dual 34 carbs (EMPI) with the equalizer tube between both manifolds and can't get a good fuel mixture. (The distributor is vacuum and centrifugal.) Tried both sets of jets. Would timing be causing this problem?? Or maybe I need to connect the vacuum from both carbs to dist?

Any help would be great!

Weber 34 ICT with plastic floats Should be set at 3.6mm for the upper limit, and the bottom at 12.1mm. Remove the top of the carb by removing the screws and gently lift the top off....the gasket should stay with the top. To check if the inlet/shutoff valve is in good order, turn the carb top upside down (so the float closes the valve, and blow into the fuel inlet (where the fuel line was connected) you should NOT be able to blow through it. If you can, the seat and the valve should be replaced (comes in the rebuild kit) If you can't you are good to go. Turn the carb top back over in it's assembled position, with the float hanging down..You measure from the gasket (still on the carb top) down to the top of the float this will be the 12.1 mm measurement......bend the tang till you obtain this measurement. Next lift the float untill the tang just closes the valve (not tightly) and measure from the gasket to the top of the float. Bend the tang to get the upper limit of 3.6 mm. Hope this helps you.

Your fuel pressure should be between 2.5 to 3 psi to be correct for these carbs.
