this is from memory so bear with me.
Remove your primary boosters, there should be two small brass orifices in each one, clean the hell out of each one, the smaller one if your idle bleed, it needs to be spotless, and has a tendancy to fill with crud. Next follow that orifice through the main body, remove your idle screws and blast the passage ways clean with carb cleaner. When you set your idle feed screw go all the way in and back it out two turns to get a baseline, tune from there with a vacuum gauge. there is most likely crud in your idle bleed and no amount of magic acid pressure wash will take care of it if you don't know what you're doing. The other brass tube is your emulsion circut and should also be spotless for best cruise performance.
