As promised in # 4.   So you are scared shirtless -- the pump is too compli=
cated , you say  --good -- then the reward at the end is sooo much sweeter.
Firstly the saying "timing the pump" is a bad saying.(About that some other=
 time) we are timing pump to engine.
How many things can we adjust. ???   here are some of them,   1. Idling spe=
ed (most common)  2 Max throttle     3. Cold start lever. 5.  Fuelling scre=
w (turn 1/4 turn at the time) is touchy. 6. Governor (sets Max RPM no load)=
 7. Timing piston (change shims)  8. Fuel regulator (done by adjusting spri=
ng pressure on piston).   Note Governor screw and locknut has left hand thr=
ead. 9. And the biggie the slotted holes on pump mountings.We turn the pump=
 --a pencil line move makes a difference. (more on that some other time.   =
Every thing I say I have done    --- but all this applies to  BOSCH VE pump=
 068 130 107 xxx  This is VW number. we can go by bosch number as well.    =
  The rabbits here are happy as anything and all gave up smoking.     "I ca=
n hop and I can run . See me hop and see me run -- it is fun fun fun ".    =
    Hagar.
