Weber problem Options

[stock93]

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?

Does it drip while idling or with the engine off?
If it drips while the car is NOT running, then it could also be the neede/seats (float valves).
And while you're here, IMHO 36mm vents are a tad large for a stock 2.0.
Consider mixture velocity thru the carb- as the venturi gets larger (diam.) the air moves slower down thru the carb (for same amount of suction).
If you make the vent daim. smaller the mixture velocity will increase (at lower rpms) and can possibly take care of all of your hesitation.
You get better mileage too..it can possibly lose you a snippet of top end but you may gain power and smoothness all around.
And get some velocity stacks!! (IMG:style_emoticons/default/smile.gif)
