It was fine before I played "Adventures in Compression Testing". There was only a small bubble in the primary filter then.
For what it's worth, I had to replace the hand pump because it failed. That initial start up after the compression check was difficult because I couldn't bleed the lines.
As to the pnuematic governor...I have a clear plastic line running from the back of the IP to the breather. Would that be it? If so, how can one check for failure? I understand that it serves as the load line for the IP.

I PMed you some info on the Pneumatic Governor. I do not know how to trouble shoot them.
Actually if the Lift Pump Valves were leaking or the Pump Piston was worn (it does not happen very often that the Pump Piston gets worn unless dirt went thriough it; when that happens the sides of the Piston get scored up) it would be more noticable at idle speeds than at higer rpms.
Because Fuel has more time to leak past at idle speed and the Fuel Volume per minute is lower.
If you look at that info I sent there is some test proceedures for the Fuel Supply/Lift Pump; although not for your specific year.
