Nothing about that carb should make it stay at a 2k idle repeatedly unless the primary throttle shaft (controlled by the gas pedal and cable/linkage assembly) is open. Look down in the front bore and see if the blades are partially open. Disconnect the linkage arm from the carb and make sure there is full travel in both the foot feed and the carb linkage and that once unhooked the front throttle blades are closed and near horizontal in the bottom of the carb. If the front butterfly is at or near vertical then its not the choke either.

The only way a carb can generally "idle" that high is if the gas being fed in is in atomized/mixture form, as raw gas would more likely drown and stall it, not rev it up. So its likely not a stuck float. The timing wouldn't make it go from 700 rpms at idle to 2k either.
