Weber problem Options

I have a 2.0 type IV engine with 44idfs on it. I was going to sync the carbs today and noticed that even when not pumping the throttle the accelerator pump drips a stream of gas down into the throat of the carb enough that its pooling up a bit on the throttle plate. I'm getting popping back through the carbs. Timing is spot on and the valves are correctly adjusted. I take it this is a problem and they arent supposted to do this? It also smells like its still running to rich. I have 135 mains, 200 airs, 55 idles, 36mm vents, and no velocity stacks currently. Mixture screws are set 1.5 turns out. Its also hesitating from idle to around 3K rpm if I step on it hard like its flooding out. Time to put kits in the carbs? Does the jetting for the accelerator pump need to be changed or adjusted?

This is a tough issue with her car. I found two GREEN wire terminals leading into the cap and a coil wire hanging on by the dust cover. Of course when I pulled two wires off to check them, I didnt pull the two that where green with algae until MUCH later. The chances that I would pick the two good ones is pretty slim, but I managed to do it.

Anyway. She said that it ran fine. This leads me to beleive that it was tuned fine at some point.. so the question remains: what changed between now and then ? I have tested a new coil. It currently has a different dizzy in it. I have hot wired the new and old coil to eliminate any voltage issues to the coil. I have checked all grounds. I found the floats to be WAY off. Somebody measured them with the ball collasped.

We will see. The dyno I need to do this only exists in a few shops. The 4 gas analyzer wont tell you anything that is load sensitive like this. I can make the car very crisp off idle, but it will still stumble on acceleration. I need to check the fuel pressure while driving.
