If I can toss another tid bit of info, if you run a racing fuel, VP or Sunoco, in some cases the dye from the fuel turns into molasses and really goops up the same passages and ports.

The temp and humidity have been pretty high here in Dallas, and I tossed a plastic bag over the carb overnight to keep crap out while running the valves. The fuel evaporated, but the dye stayed behind. The engine ran very sluggish and wouldn't idle. Pulled the carb and spayed and squirted every opening. Blew dry and voilà, ran great.
