Sadly that won't clear a blocked idle jet. Because by the time you're at 1/4+ throttle there isn't anything even trying to flow through the idle circuit anymore. It's all headed through the mainjet past the needlejet. The carb needle controls how much gas gets into the engine. Once you hit 3/4 throttle or more it's all the mainjet that decides how much gas is going into the engine.

The pilot is the smallest jet, and thus the most likely to gum up. Sometimes you can just take the float bowl off the crab, and stick a small flathead screwdriver in there, and twist out the idle jet. Then you fill it up with carb cleaner (its just a little brass[not sure of metal] tube with threads on the outside} and blast it with compressed air. Don't launch the jet across the room.

This should knock the blockage out, then you reinstall it into the carb, check the float height, install the float bowl and start it up again.
Of course I'm generalizing from a single example here, but everyone does that. At least I do.

Yeah, I might have just been lucky. Mine was not mechanical, or scientific. Just lazy. And truth be told, my problem was not at idle, but dogging down when I tried to apply max throttle.
