I need advise. Wd45 governor/throttle woes.

Question. When the tractor is not running. Run the throttle low and it pulls on that spring under the governor cover up front. Should it be stretching the spring or should that spring act as solid linkage until the governor influences it? It stretches mine and doesn't move the bottom lever at all. I'm wondering if that cross over tube with the rotating linkage that goes under the fan is full of grunge? Or maybe the spring is old and weak? I pulled out the alternator/governor assembly and that all looks in good repair.

Rewind. Here's my situation. I got my first orange tractor a few weeks ago. Got a good deal on it. The guy I bought it from said the governor would loosten up and start working once I ran it more because it's been sitting a few years. Now when I was driving it around his driveway I could slow the throttle down at the control but not speed it up. Long story short, I took it home and used it and the throttle control does nothing. I set the throttle by putting the linkage on the carb side where I want it, climb on the tractor, and feather the clutch to keep it from killing when it's under a load. That got old and today I pulled it apart.     

Yup. Mine is bass ackwards. I just copied it the way it was when I got it. I'll look at it again in the morning. But I think the governor arm does go forward like an inch and snap back. Assuming it does, where do I look next?

Oh yeah. I went in baby steps taking it apart today. I did see the big spring under the tank. The linkage does not look especially worn. Now on the governor lever by the alternator there is a little clip should there be a spring on that?

There's nothing attached to that clamp on the governor arm is there? Because there shouldn't be anything there. Looks like a PO was jerry-rigging something to get around past problems with the gov. instead of fixing it properly, I would just take the clamp off. I see there's an alternator on it also, the elbow of that arm looks real close on that side, it's not hitting/binding on the bracket or alt body is it? Check the position of the arm for free movement throughout the range of the throttle lever.

Just because the vertical governor arm is bent like that doesn't mean it's wrong. The key is the synchronization of the arm hole position to the carbs throttle shaft opening. Many arms have been bent like that and some the other way. Synching is key, not what it looks like.

Sugarmaker, that is with the throttle all the way down. It just stretches the spring and does nothing else. Is that supposed to do that?

Does this stuff look correct?
