Get the nail-polish   And clearly mark sprocket on both sides to get an eas=
y way of finding timing mark.Then put a mark on sprocket where a big hole l=
ines up with bottom bolt ( 1982 to 1984.) 1980 is got to from under pump.A =
socket will loosen bolt You must be able to turn pump easily later so remem=
ber the tools. When we get to turning the pump , remember to loosen the 4 l=
ines on pump and retighten after each move. Now it is time to turn flywheel=
 to TDC # 1 cyl. be accurate  .. .If injection pump mark and sprocket mark =
does not line up , move pump. Be accurate.  Then draw a straight line on wh=
ite paint at the middle.Mark both pump and mounting plate. Be accurate.    =
  And now we go for a testride  using a small container. (I use a 2.5 gallo=
n gas can  ) from walmart.Run some line from pump to can ---both return and=
 fuel. If you can, use a small inline screen in line just before pump.    C=
heck throttle for "FULL" travel. and away we go.  At full pedal it must smo=
ke. if it does not we adjust fuelling crew, as follows.   Loosen locknut an=
d turn all the way in, then back out 2.5 turns. and lock.  About 4 turn is =
all we got to work with(thats full range)  Each time reset idle as follows.=
Set so slow engine shakes , then carefully speed up to shaking stops.As slo=
w as possible , otherwise pump will run away on you..(not dangerous just us=
e brakes).If not in gear use key.When she smokes real good at full power , =
but still lacks power ? this is what we do. Fill container with a mixture o=
f corner diesel and Aviation Ashless Dispersant engine oil say 25 % by volu=
me of lube oil as heavy a grade as you can get 100 0r 120 weight and mix we=
ll.If you cant get AV oil use a heavy straight car oil.     And a testing w=
e go.        Number 3 may follow.    Thats where the "MEAT" is.      Hagar.
