The throttle lever is linked to the throttle arm which clamps to the governor arm. I pull all the way back on that so the throttle plate is fully open and then turn the governor arm clockwise so it is fully pushing in on the governor cup. This would mean that if the throttle opened itself as far as possible, it would be pushing all the way in on the governor. This is the correct configuration, as far as I can see.
The spring setup is simple. There's a bracket with a rotating arm, which the throttle cable works back and forth and connected to that is a spring which goes into a hole on the throttle arm. There's only one hole in each piece, so the governor spring can't be off. The tab on the rotating arm is suppose to be bent in or out to adjust the spring tension to control the full throttle rpm.
