Hi Sparker, at a glance it looks as if the choke shaft needs to be rotated 180 degrees. Pull out the butterfly, rotate the shaft and refit the butterfly, it should then work. Or, put the linkage in the other hole on the plastic shaft, either way it appears as if the shaft is at full extension at the moment, and i'm pretty sure the shaft needs to rotate counter clockwise when engaging the choke.
Cheers, Ted
