Holy dog balls privates, do I have news!!
So I checked the valve lash for 3 and 4. About .0005 off. Readjusted anyway. Then checked compression on three. Number three only showed 180, just like last night. So I'm thinking the worst. Threw some oil down the hole. Too much, in fact, and that put the compression to 300 psi and filled my compression tester hose with oil. Cleaned that out, figured what the heck, I'll test 4. 4 was like 185 now, wtf?
After that I said screw it, and put her back together and ran her up to operating temperature. Took a LOONG time to clear out the oil smoke from that cylinder, man it was thick for like 5 minutes.
Anyway, back to replacing each plug each time, only testing one hole each time, I came up with these numbers, 6 to 1. 190-190-185-190-180-185 And now I was baffled. And so I called the Datsun guru who said those are fine numbers, don't worry about it. And do you think I could let well enough alone? Of course not! So I yanked all the plugs out like you're supposed to do for a compression test. And here are the numbers I came up with, 6 to 1: 225-220-221-220-220-220
Which made me a very HAPPY panda!
I think what I did last night was I had the number one spark plug in still when I tested three and four, which slowed down the cranking. And then I took it out and tested the rest. Anyway, somehow I screwed it up. Wynona is fine! Thank goodness I'm a moron!!
I also replaced the adjustable $30 fpr from ebay with the factory fpr tonight. I don't have a gauge on it, ran out of time, but so far it seems to run much better. It held vacuum quite nicely, thinking it's probably going to be just fine. I may spring for a more expensive good quality fpr that I don't have to adjust every 2 seconds. On the other hand, it worked great for 2 years on Ugly Betty, so could just be that's how long the internals last. Still, the Nissan factory regulator should last another 10 years as long as it's not leaking. And it's not.
So that's the story. Much happier now, going to drive the wagon to Cheney and go have fun with Rose and the dogs!
(She wants everyone to know she was awesome and not a bitch!) 
Ballsy or stupid! It had been running decently most of the week, but I do wish I had figured out that injector dropping earlier. It's on the list for checking out today, pending a compression test think I'll probably be okay.
