Not going against wisdom here, but I'm a strict believer in not poking wires into holes in carbs. Sometimes you ding them up, or make said holes wider. Since carburetors are metering devices (mix a precise amount of fuel with a precise amount of air), when you do those things, you may inadvertently mess up the ratios. I find a good soak in simple green (you can dilute with a little bit of boiling water if you want to, heat loosens things up, too), followed by a good spraying of the carbs with 120psi air from a nozzle (make sure to get EVERYTHING. ALL of the holes, ALL of the jets, everything). And then, do it one or two more times.
Make sure you can see a prick of light through the pilot/idle/slow jet. Make sure you have a consistent size hole through all four main jets (I had to use a bamboo skewer to finally clean one main jet out....bamboo is not harder than brass, wood works, too)
Also, don't forget to take out your emulsion tube. Sometimes they're stuck in there, but boiling would help to loosen it up.
