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.  Fueling screw=
 (turn 1/4 turn at the time) is touchy. 6. Governor (sets Max RPM no load) =
7=2E Timing piston (change shims)  8. Fuel regulator (done by adjusting spr=
ing pressure on piston).   Note Governor screw and lock-out has left hand t=
hread. 9. And the biggie the slotted holes on pump mountings.We turn the pu=
mp --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 pu=
mp 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.

        Hagar.

PS:  I did the 130 109 pumps as well ( on the 1.6L turbo. )
