I would search the site for turning the fuel up and you will get several threads and some with pictures and diagrams.
You have two nuts locked against each other on a threaded shaft that connects inside to the pressure regulator for the IP.
Unlock the two nuts WITHOUT TURNING THE THREADED SHAFT. (THIS IS IMPORTANT/
Once the nuts are unlocked to lower the fuel delivery rate, you first back the outer nut off and then turn the inner out counting the flats to keep track of your progress. When you have turned it to where you want it to be, you hold the inner and tighten the outer against it.
You will need a "TAPPET" wrench to hold the inner as it is a thin nut. The size is 1/2 inch, and you may have to grind it even thinner to fit. (I did on mine.)
I defintely would read some of the threads about this before doing it and if you are not sure, download and read the manuals.
You can download the deuce TMs including the non turbo engined variants at

report back and if you have any questions ask them before you get into this.
