JD 3320 Won't Maintain Throttle

[DrZaius7]

You can get a wrench on the nut that needs tightening without taking things apart. I've done it on my 3320. Poor design that needs readjusting occasionally.

I haven't had a chance to dig into it yet...can you reach the nut just by opening the hood?

I went in along side the throttle handle through the slot it moves up and down in on the dash. didn't have to take anything apart.
