The bottom line though is if it runs well enough to cut reasonable

If it simply doesn't tickover smoothly but the revs hunt up and down
it could be running properly?

I have a Briggs&Stratton-powered cheap genset.

It hunts (vroom-vroom-vroom-vroom) when not electrically loaded, i.e. very
little mechanical load. Put a bit of load on it and it settles down.

OTOH, if you aren't sure you have attached the governor springs right: check
that. I tried to replace a missing spring with random springs selected from the
random spring box, and it didn't run anything like nearly right until I bought a
(surprisingly expensive) replacement part. Lever length, hardness, spring length
need to be spot-on, or very close. And there's usually a line of holes in which
the bits hook, get a wrong hole and you have just set it to "perfect for a
snowblower in the tropics" or whatever.
