idle problems

I have just put a new carb. on my samuri and am having idle problems. If I get it to idle high enough when it starts to keep running then when it warms up the idle increases way too much. it would seem this is a choke problem but I have been over it and not find any inconsitincies with the carb I just took off? Is the an adjustment or what would cause this?

I found the idle as shown and it did help.... however a new problem or should I say anaditional un niticed problem has surfaced. The Idle up aculator. It work s as my book says.. turn on my lights and it presses down and incerases the idle then turn off the lights lifts up and decreases the idle. but... when I race the engine at say 3000 rpm for a little bit usually 1/2 min is enough the aculator presses down on the gass and then wont let up. the only way I can get it to let up is to disconnect the vacume, shut the engine off or bg the engine down (i/e break without using the clutch) what could be causing this???
