Here is the inside of the top cover of the pump. Nothing out of the ordinary here...

Here is the throttle shaft. (Yes, it's upside down...) This is one of the most common sources of
a leaky VW injector pump. And it is the most easy to fix! |
| Here is the governor. It is remarkably simple. It is either on or off. It
is off in this picture, meaning it isn't doing any thing. |

Here is a picture of the governor when it is doing its job. Notice that it
has pushed the black rod out, and it will take over the throttle. The throttle has
springs that the governor will stretch. I had a cummins disel truck engine with
a faulty governer. The truck had a top speed of under 60mph, so the governer
was always being engaging. Sometimes it would get stuck on, and wouldn't
disengage until I let off the throttle. The engine actually stalled out once. In
my opinion, the governor isn't really needed, and can be removed. |

Here is the timing advance mechanism. The Cam Disk rides on 4 rollers. Only
one roller is shown. The timing advance mechanism rotates the 4 rollers and
affects the start of injection. |
