I've been asking around, searching on the internet etc and I can't find the answer to my question. Then I remembered your a guy that knows about old cat engines.
I have a D6 C (76A) with a d333 engine. The engine is short on power. Can I turn the pump up on this engine to increase the hp? The pump has shims on the back side of the fuel rack rod, is it just a matter of moving one or two from one side to the other or is there a whole bunch more involved?
