You need to verify flow through EVERY passage, or risk re-doing it (some people SEVERAL TIMES.)
I use fine wire plucked from wirebrush, held with needle nose pliers, (in addition the pilot sized mounted drill bit)
Then aerosol brakecleaner, OBSERVE THE STREAM, concentric, symmetrical. (Of course, don’t “shoot your eye out”).
EDIT: The Brakleen is not meant to replace carb cleaner, but rather, a cheap aerosol passage test tool.
