    Just a hint sense I consider my self the King of pumping up a deuce engine...... The adjuster rod faces the radiator and might be covered with a tin cover and 3 bolts with safety wire. ONLY brake the jam nut loose (a thin 1/2 in wrench will HELP!!) and turn the inner nut. DO NOT ROTATE THE SHAFT IN ANY WAY!! If yo do that you could drop the rod that is connected to that shaft and then you ****ED IN THE A. There should be a hex in the center of the shaft to place a star wrench or what have you so you can make sure the shaft does not rotate .

    Just remember, adjusting the max fuel rate without monitoring your egt's, is flirting with disaster.

    Unless you read the dozens and dozens of threads on this topic and or understand what your doing and monitor your egt, don't do it!

    That screw is NOT a horsepower output dial.

    Will consider myself advised. Also will search on this topic and see if I can't find out more info.

    If this adjustment raises the EGT too much, I might not consider it any further. Right now, hammer down on the flat and level I can pull 2500 rpm, maybe 2600. That's already to the limit, in my mind. Any more and you're gonna get hurt, or hurt the truck.

    most of the time you can go 2 flats no problem (1/3 of a turn) any more then that OR if your truck is set a little high form the Military of who ever..it could be too much off that bat. DH is correct you need to know what you are doing and have a pyro. If you turn up the fuel you really should have one installed.

    Well I have an oddball. Older A2, non C turbo (still a turbo). It has fairly recent filters, but I'm going to change them again before doing any real adjustment; and will install a pyrometer as well. This truck is GUTLESS. I mean I can barely hit 2400 rpms on the flats, even in lower gears, no load. I know the 11.00 rubber is a slight extra drag, but they are also highway radials and only singles, so that should help a little. The truck runs smooth, starts every time no matter the temp (even when it was -10 this winter). But it seems to idle pretty low.

    Here are a few pics of my pump:

    HPIM0904.jpg
    HPIM0905.jpg
    HPIM0906.jpg

    As you can see my pump is nothing like the one pictured. Where is the adjustment screw on this one?
