generac xg8000e low voltage/ engine wont rev up

Question

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 air compressor 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 ?

If you have small hoses connecting intake manifold to governor replace them all. A collapsed, kinked, blocked or pin hole leak in a system can lead to a non responsive governor. Replace all the hoses then try it again.

Ok thank you it check that out when I get home I'm wonder would it be worth it to try taking that out and hooking up a power control one to keep it at 60h and 120 Volts like a  Power control module with a 12 V electronic actuator to control the engine throttle .
