Hey Lewis!
If you've adjusted the idle screw on the back so its completely out, and your idle is is increasing when you adjust max fuel screw - then all you can do is make an adjustment on the throttle arm.
Assuming you have wound out the stop screws - the ones that limit the travel of the throttle arm, both min and max travel.
You can take the arm off and move it back one spline, but you may then not be able to reach 100% throttle unless you make some mods to make sure it has full max movement - you may need to bend the arm, or grind some bits away.
I'd very careful though, sounds like it is very nearly maxed out, and it won't take much for you to turn it up and bit and get revs hanging and the pump running away on you.
