B3030 - not enough rpms - throttle adjustment?

[cart99]

Recently I've been having throttle position issues. With the throttle lever at maximum position, I am barely in "PTO range", and what's worse is that as I run it, it creeps back to a lower RPM.

Do I need to tighten the cable or is there some other way to adjust both the "stop" position and the lever tension?

Any help would be appreciated.

Thanks!
