more fuel for Detroit 6 & 8V 92's

Detroit 6&8V92:

Adjust the no load speed up.
Back out the buffer screw a few turns.
On the back side of the governor is the cap held in by 2 bolts, take that off and you have access to the idle control and the top no load setting.
Loosen the small 1/4" nut at the end pack and back out the idle speed screw about 4 turns.
Loosen the large clamp nut with the 4 notches in it on the other end of the pack. then screw in the entire assembly 3-5 turns. Tighten the large clamp nut.
Fire engine up and adjust the idle screw to just below the desired idle. Tighten the idle screw nut.
Adjust buffer screw to desired idle and so when you stab the throttle the gov doesn't search.
Put cap back on and run it around and adjust from there.
You can also get better response by running a tight rack but with you sand jockeys playing with that makes for a good runaway so just jack up your no load adjustment and try to keep it below 2600 rpms at top no load.
