On most newer generators the only control the user has is the low idle speed.
The governor does the rest.
The low idle is set by the screw while measuring the output voltage and get cranked up till it measures then minimum line voltage.
Down here where we have 240V & 415 V they get set to 220 V
Then you hook up a heavy load & measure the voltage again as the generator accelerates.
If the voltage drops then you crank up the low idle a bit more.
If the carby throttle is sitting against the throttle stop & the engine is racing then some one has screwed it up.
Not uncommon to have one come in where the dopey owner has wound it up to 4000 rpm which burns up the output voltage regulator.
Also double check that the governor arm is set correctly on the governor shaft.
A racing engine will result if it is set up backwards.
I found the missing link. As someone else mentioned (maybe you) the spring on mine looks too thick for where it's located. My guess is the previous owner lost the thin throttle spring. I finally found a pic of what I think it's supposed to look like.
