Jimmy... Sounds like you have the opposite of my problem. It looks like I'm going to have to turn the yoke towards the carb.
I haven't taken the gov apart but I've read the instructions a couple of times and one of the things mentioned was making sure that the large spring was not only hooked in the correct hole on the rock shaft, there are 2, but also that it was facing the right way since apparently the hook can catch on something if it's put in "backwards".
Can you manually operate the gov from the carb side of the engine and get any control over the engine speed? That at least would tell you that the gov is not restricting the throttle movement.
Other than that, I'll defer to the other guys on here because it's clear to me that they know a lot more about this than I do.
