Re: New vaporstat
very odd. I'd be inclined — this summer! — to take it off the radiator and the pipe, and see if the internal valve is connected to the handle. Or if you're a little braver, leave it on and unscrew the mechanism from the valve body (the big hex nut under the punched plate). Be gentle. Take pictures. Use a very high quality box wrench if possible — don't even think of using a pipe wrench. You may need a backup wrench on the valve body.

I did eventually get it working. It's cutting out at about 4 oz and back in at about 1 oz.

Re: Air in boiler feed water
Given your slightly unusual situation… I'm not sure there is a good way to completely avoid the problem.
However, one thing you can do to at least reduce the nuisance is to make sure that your pressure reducing valve is set correctly and located properly and, if not, close the feed to the boiler and leave it closed — assuming that you have no leaks in the system causing it to lose pressure.
So.
The second approach is the better or the two, and therefore what I suggest is that you close the feed to the boiler — and leave it closed while you observe it for a day or two. It should hold pressure (if it doesn't, you have a leak on the heating side — which is another and different problem which will need attention). If this works, there's no reason to open that valve again until you are done with the work which requires shutting the water off.
However let us consider the piping and valve arrangement. The pressure reducing valve — autofill — should be as close as possible to the expansion tank, and both of them should be on the inlet side of the main circulating pump. The pressure reducing valve should be set to the same pressure as the empty precharge pressure in the expansion tank. If this is so, then there should be no water feed to the system — again, unless there is a leak…

Yes, but I've already looked at the 49 that rank above this;)
Re: Wirsbo return manifold leak
Thank you all so much - this all already quite helpful. I will report back once my daughter goes to nap ( complicating this whole mess is a energized 15 month old who doesn't understand why dad is sleepy and distracted).
Much appreciated
Re: The "equalizer" is mis-named. It does nothing to equalize anything.
Just taking a guess over here. There are probably systems where there is not much of a pressure drop between the boiler and the end of the main. Well piped, smaller system, with nice clean water in the boiler... Probably not much of a pressure drop. But take a larger boiler, that might be running at higher pressure than it really should, with a very long main, that might be undersized, with wet Steam which contributes to pressure drops, and there might be a significant pressure difference between the boiler and the far end of the main. Which would certainly lead to water being pushed out of the boiler. To accommodate all systems and scenarios, the A dimension probably became the industry standard. Just a guess

" and I found that the main filled a little quicker, like in 8 minutes instead of 9. No big deal, right? "
" (i) My main is vented well. I can speed it up a little by playing tricks, but there's no need to add more vents. "
Not tricks, better main venting. Reducing the boiler run time by a minute every cycle, I would think it would save a bunch of fuel (Money). If your boiler runs once an hour that's 24 minutes a day that you are not paying to burn fuel to push air out through a restrictive venting system.

Re: The "equalizer" is mis-named. It does nothing to equalize anything.
I sort of get the feelings, without doing proper experiments, that there is one set of rules for all systems. Small residential to large commercial. Well piped, under pipe, over piped..... Take a very large commercial system, maybe under piped and with very dirty water. Good possibility there will be a significant pressure drop by the time the steam gets to the end of the main.

You can walk around all day with your jeans on an no belt and your pants won't fall down.
But if you start working overhead and sucking in your gut your pants may fall down.
(Unless your fat like me)
So I wear a belt.
Thats how i think about equalizers.
You never know when you might need one.
Who wants to take the chance??
