Help Won't idle Options

[1bad914]

Carbed 1.8 motor, the valves are adjusted, the timing is okay, new plugs, new plug wires, 009 dizzy (it's all I had available) dellorto 36 carbs freshly rebuilt. Fires right up, blip the throttle to warm up and let it drop to idle and it drops down and runs for 10 seconds or so and then starts to stumble and dies.

Pulled idle jets and cleaned them, adjusted speed control screw to increase idle, played with timing, I get an occasional back fire from the 3-4 side of the motor, this is my first set of dells, I hear they are easier. Dwell is a little off, but not really bad (45.9). Any ideas? I have installed and tuned many Weber VW/Porsche carb setups, I even have the Tomlinson Delloto tech book!

When I crank it up and hold the throttle on it it seems to be strong, it pops a little, but probably a little timing.

Help!

I have set of webers that I am about to rebuild and throw on! (IMG:style_emoticons/default/mad.gif)

Dells don't use a T fitting for the fuel lines, they have a banjo fitting on one carb that splits the fuel and sends it to the other one. The carb that gets fuel first is acting up, that tells me that the fuel is making it to the other carb. Yes they have floats, I set them while rebuilding. I walked away from it for awhile, developed a little JAVA code for work and thought it thru, I may just re-build the webers and try them, I need to do that anyways, so that would elimenate the fuel issue.

Any other ideas?
