I have the drawings uploaded.
The first page is the parts list. Compare it to what you have, and let me know which parts need to be replaced.
The second page shows the 2 adjustments I was talking about. The sensitivity is the screw you were looking for, and the speed adjustment is a nut.
Test both to make sure they will adjust, and are not froze up. If they are froze up, we will need to replace, them, also.

Just reply to me here to let me know what we need.
That part is listed as obsolete, and is no longer available.
You might could try some internet searches, but you are going to be hard pressed to find one, short of running in to someone who has a genset that they are scrapping.
