So what about the other formerly very good motors? Kohler? Wisconsin?
I've
seen a lot of those on commercial/industrial equipment in the past.

You'll see the Kohler's/Wisconsin's on heavy duty marine/industrial/
emergency equipment and those that I've serviced are extremely high
quality.
I have noticed that some of the later Kohler's look alot like Toyo's
offerings.( Toyo motor works of Japan puts out a near clone of Honda
and seem to be just as good.)
Even though they(Kohler) still carries a "made in usa" badge.

I've seen both Kohler and Wisconsin used in emergency evac/marine
pumps and on older Bearcat scooters and swamp buggies.

My apologies to all if I've come off like a troll.

Ya know, I went to Home Depot the other day and looked at lawnmowers and
holy crap, you're right! The B&S motors *do* have cheap flimsy plastic carbs
with primer bulbs now! I always had *great* luck with their stuff, I dunno
when it changed but it most certainly has. Maybe my B&S stuff is older than
I realized.
