i believe it is on the front of the governor housing right where the first injection line comes out.

It should have a cap-nut on it.(unless it has been lost) which you need to take off first.

You need to use about a 12mm(10?) spanner and an allen key. The allen key goes into the middle to adjust, the 12mm spanner to crack the locking nut.

no idea which way to wind it to increase fuel.
