OK... I'm sorry for the confusion. I am the OP and I posted all of the pictures. The carburetors I am having trouble with are BOTH styles. The picture I posted last is just the one that I actually removed the ball from.
The part number for this carburetor is 591925
I posted this - https://www.lawnmowerforum.com/threads/any-idea-how-to-clean-this-jet-on-walbro-lm-series-carburetors.71610/post-447161 but would you like a less close up?
For every other jet or "metered passage" that works great. I do the exact same thing on all of them (except the "watch your eyes part" ... I always forget to do that until it's already too late :) )but this one sits behind a ball that the factory pressed in after drilling the passages and since...

I had a zero turn come into the shop. The guy said that they had had the engine "rebuilt" and since then no one could get it running. I finally got it running - it had a lot of electrical issues - but once I did, it wasn't running right. Without the air breather installed it runs OK, but it is...
