Yamaha rt 100 is not idling

[highjump]

hey guys, I bought a second hand yamaha rt 100, not running. I cleaned the carb, put a new spark plug in (has a great spark now ) but I can't seem to get it to idle. Have to keep playing with the throttle otherwise it stalls. Any ideas

Idle jet in the carb is still plugged.

Pull the carb again, remove the jet, and spray carb cleaner through it and every single passage. Keep the cleaner away from any rubber parts you don't want stretched-out beyond use (like bowl gaskets, air-cutoff valves, and slide diaphragms).

+1 to the 'Hawks comment.

If you are very careful, you might also use one strand of copper wire you take out of a bigger gauge. Use it to physically clear the orifices (orifi?).

The copper is too soft to hurt the aluminium holes, but stiff enough to clear the mung out.
