generac xg8000e low voltage/ engine wont rev up with load to increase volts to match load .

need some help trouble shooting the thing i used a muilt meter to test HZ and volts got 55HZ 98 volts
went under gas tank turned a screw got 62Hz and 126volts now at idle/ no load.

Plugged in a flood light got 61HZ 123 volts then plugged in small aircompressor volts dropped to 98.
I reach up under the fuel tank pushed on the gover spring and volts shot up to 140 with the air compressor running so i know its got the power but its not adjusting under load ?

Need ideas im out ?

Id throw it in the trash and buy a better generator. Generac sucks at making portable generators. Imo


2007.5 dodge cummins 6.7 liter. Chevron Delo400 15w40. 7000 mile or 250-300hr intervals.

Lol yeah Generac's quality has dipped a lot recently.

I've had a Champion for 4 years that I bought at Costco for next to nothing. Works like a champ and has never let me down.

It is noisy as [censored] though.

I think you were right.

i tighten up the spring and it seems to be working great now. idle 61.5 HZ 119 volts flood light load 60.68 HZ 121volts light and 15 amp air compressor 60.68 hz and 122 volts. Thank you.

might have been weakening over time and i never knew it

To every one else who makes a good 10k watt one then? and who want to mail me some cash to help buy a new one?
