Dual carbs, Fuel delivery Options

[arkitect]

I've been working on my dual carb setup for awhile now. Thought I would have them sorted by now. Having trouble with getting fuel to the passenger side carb. I can see the fuel going into the driver side fine but the passenger side just barely one barrel getting fuel.

I am using the Weber IDF40 carbs with a faucet electric pump. Maybe not enough fuel pressure?

After the fuel filter I have a single to dual fitting to split the fuel line to the carbs. Stronger pressure to one side?

Any comments would be helpful. Thanks.

(IMG:style_emoticons/default/agree.gif) Did you check the floats in the carbs before you put them on? Have you had them apart or just bolt them on?

GENERAL INSTRUCTIONS: Float level, in mm, typically refers to the distance from the face of the carburetor top cover to the float. With the top cover held vertically (float pivot at the top) and the float tab (Lc) resting against, but not depressing the spring loaded ball in the needle valve, measure between the face of the carburetor top cover to the top of the float. On carburetor models where it is required to remove the float to replace the top cover gasket, the measurement should be made with the gasket in place to the gasket face. You need to set the floats to 10 mm closed and 32 mm opened as shown.
