James, your post No. 8 looks like the ticket to me. Do you have the governor hooked up and operating? Is it a vacuum or mechanical governor? For safety's sake, you should be able to shut off the engine from outside the engine compartment if you're going to drive it down the road - this uses different vacuum than a vacuum operated governor. So.... yes, you should try to get the vacuum lines connected. Also make sure the engine can breathe - i.e. crank vent.

As far as the timing goes, remember it's not a race car and it's not supposed to be rocket science. One drop per second is what you'll get if you use exactly the same setup as the person who wrote 'one drop per second'. You'll have enough fuel in the secondary filter for maybe two tries before you need to pump it up. You should see a gush then a steady run then a dramatic transistion to a drip. Set it at that transition or maybe a half degree past, then watch your performance and fuel mileage. Tweak if you really, really want to as the exact spot will be where your car likes it, and depends on what shape the injection pump, injectors and timing chain are in.
