In order (some of this was just wanting to maintain it, and not necessarily directly addressing the running issue)

Hit something last year and it died suddenly on the lawn
- Trouble starting thereafter
New spark plug
- No change to starting/running issue
New air & fuel filters
- No change to starting/running issue
New fuel pump (Briggs & Stratton)
- No change to starting/running issue
- I did lose the bolts during that installation and the pump isn't attached to the side of the motor/plastic, where it should be, but it's not flopping around or anything... are they that sensitive?...
Checked original carb, looked okay...
Replaced original carb seals
- No change to starting/running issue
Fully replaced carb (B&S)
- Staring issue cleared
- New Issue: Starts and runs beautifully for 5 minutes, then only runs fully choked
Removed gas tank, emptied/cleared of debris, refilled with fresh gas
- Siphon was not clogged
- No change to new issue
Removed solenoid under carb bowl; NOT clogged, no debris in bowl
Motor has under 150hrs
Battery was new last year
Fuel filter is full/remains so, as far as I can tell -- I believe it is getting fuel to at least there, and the issue is not upstream from that. I think.

NEXT MOVES

I plan to replace the intake manifold, as there have been suggestions from my original post about an air leak there
Other than that, I've seen a couple of votes for checking the valve spacing -- I'm wondering, would a hard hit, knock the valves silly, is that a thing/my problem all along?
- Please tell me what to use, exactly, to replace the gasket on the valve cover after checking the valves

EDIT -- CURRENT STATUS

This is the issue nailed down, currently -- it chugs and craps out when cutting through thick grass. It starts/runs perfect, cuts low grass no problem. But as soon as the blades are under any type of decent load, it chugs/dies. (Already has a new engagment belt and cord)

HELP: What movie was this, is it a fever dream?

The memories are from perhaps the early 90's. I recall flashes of scenes, but no context, plot, names, etc.

The main character is a pre-teen. Not sure male or female; I think male. There is some central thread about... hair, or that person's hair. And some level of miraculous growth of the hair. There is also a character that is an old man. I think. I don't recall if it's Einstein, intended to be Einstein-like, or what. It may not be at all, it may just be an old man. But I recall some relative link to Einstein. There is also a dream-like scene with gold orbs, or gold flashes, or some other magic particles swirling around the child character. I also have a flash of a scene where the child is looking at a photo of a person: in the photo the person is looking out a window, downward, toward the photographer.

Help! It's been gnawing at me for about 2 decades...

JD D110 Mower only runs fully choked...

Had a chugs-then-dies issue late last year. Installed a few things, which I'll list in a second. But the most recent was a new carb which seemed to get everything running tip top. I did about an hour with the drag-behind leaf collector and then it started running choppy again.
