Probably separate, but you'd have to look. If there is a separate choke control, then the throttle is probably set by a governor.

There's no throttle, I guess it's tied to choke?  Not really my area of knowledge at all...

Does the choke also open the throttle?   That’s common on car engines, no idea if it does on a generator.   That little bit of choke might be kicking the speed up just enough to make the UPS happy.

So you're thinking the 110v is probably its output and not relevant?  Carb issue could be causing it to bog down like that and it gets resolved by closing the choke a bit?

It's labeled for 6250 running watts and if I'm doing ~1500 that seems odd that it'd be an overloading issue.

or maybe the 110v side is overloaded, maybe try running @ 220

Sounds like you have a carburetor issue.  Maybe some plugged up metering jets due to varnish.

None of our generators or any one I've seen let's you adjust voltage.  The ones we have are all TroyBilt-ish with Briggs engines.

The UPS did switch to the generator when I lowered the choke ~10%.  But it would not use the generator at full open and the generator sounded like it was bogging down.

But engine speed will affect voltage.  At least on older units.

Not sure what the generator is but most have the ability to adjust the
output voltage and frequency.   If you have the option you could just crank
the generator output voltage up enough to make the UPS happy.   Note that is
done by adjusting the excitation voltage, not the speed of the engine.
Engine speed changes frequency.      (All of this assumes a traditional
generator, not a inverter style generator like the small Honda’s)
