According to TM 9-2320-361-20, the LDT 465-1C/1D engine is 800-850 RPM. However, I have to pull out my throttle control 4-5 clicks in order to get a warm idle speed of 800 RPM. How is the idle speed adjusted? I've searched through all the -209 and -361 series level 20 and 34 manuals and the injection pump service manual but cannot find anything at all on adjusting the idle speed setting.
I don't see anything on the fuel pump resembling an idle speed stop screw, but I know enough about fuel injection pumps to not start randomly twisting screws and see what happens. So how is that idle speed adjusted? Does anyone have a TM reference to show the process?
Lee, check out the pic. If you look close you can see where I outlined the adjustment screw for the idle. A little goes a long way. Each time you make an adjustment, wick the throttle a time or two.

Very useful, indeed....just uploaded "Multifuel engine truck operator" to the "Driving" section of the PS magazines.
It includes the first appearence of your (Kenny's) "Walk around decal" art by Will Eisner, which was in 1967.
