At least there's no more wondering on my part whether it used the steel retainer or what. Mystery solved.
Thanks TommyK! Here is another view of the cap raised up:

Not sure how lose is too lose but, you are right. For a couple of dollars, why risk it. It is now on the shopping list.

I also tried taking a picture of the meter rods retainer spring to show what condition it was in... and "lost" it in the process. Whoops... I am sure you can see how bad it looks. Just bent every which way.

On the subject of PP, I saw these hash marks on the tube where the PP goes. Do they mean anything?


Going back to a previous post...

The rods (primary and secondary) have the size stamped onto the rod, you'll need to look for it, possibly use magnification (I do, but my eyes are old).
I tried looking for the stamped numbers and they are hard to see. Taking a picture was even more difficult. It took some heavy editing to bring out the markings. On the jets, the marking is "73". But I can't really make out what it says on the rods, aside from the "3"at the top. "3mm"?
