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.

The driver side carb shoots a nice stream of fuel to both barrels. The passenger side carb, not so much - the barrel closest to the fire wall, dribbles out and the rear barrel has no fuel coming out of the jet.

So you are talking about when you turn the throttle and the fuel squirts down the barrel?
If so, that is your accelerator pump. And as mentioned above, bad diaphram or clogged jet. Or if you have the adjustable accel pump lever, it may be out of adjustment or broken.

Or do you mean you are looking down the barrel with the engine running and are seeing gas dribble?
