I checked the fuel pressure today, and it is at 29. The book says 28, so I am not quibbling and blessed the FPR. It lost 1 lb of pressure after 5 minutes of sitting.
The throttle switch is pretty neat. I managed to get the beast started long enough to get to the engine bay and hold the throttle at just above idle -- 1,000 rpm or close. The engine does shake quite a bit because some plugs are wetter than others, so it was hard to move the throttle switch with grace.
The throttle switch has 2 primary contacts, upper and lower. With the throttle slacked, only the upper one makes contact. When I moved the contact to the lower one, the rpm smoothed out a bit. Very interesting. When I let lose, back to it's normal chug, chug.
Also looked into the intake manifold and found a small lake of very dirty gasoline lying under the butterfly intake. This stuff is black!

Just what you didn't want to hear,

Klaus
