On the carb that's dribbling, what's the idle speed? If it's a little too fast, you'll see the high speed system beginning to flow some fuel. If the idle speed is down around 500-600 RPM or so, the float level is probably set a little too high. Try lowering the float a little and see if the dribble goes away. On the one that won't idle, you've probably got an idle passage clogged up, or a gasket installed incorrectly that's blocking a passage. How did you clean the carb while putting the kit into it? If you didn't use some type of solvent dip cleaner, followed by a hot water rinse and LOTS of high pressure air through every passage, you didn't get it clean enough. Solvent softens deposits, and the air blows them out. No air available- - - - -don't waste your time trying to do a rebuild!
