I will see if I can get a photo of the gas plumbing. I have 2psi service from the gas company. The step-down regulator is a Sensus 143-80-2, 3/4" connections, 1/2" orifice with blue spring. The generator is quite close to the meter. I'd estimate about 2 to 3' of 3/4" pipe from the meter to my step-down regulator. Downstream of the step-down regulator, I'd estimate about 2' of 3/4" pipe with a couple elbows and then I had a 2" "reservoir" pipe of about 3 feet installed just before the flex connection to the generator. I have not measured the gas pressure.
Could you offer a recommended governor adjustment procedure? The service manual recommends properly resetting the lever to the governor shaft, then removing the idle spring and adjusting full load speed to 58Hz, followed by returning the idle spring and setting the no load frequency. Peddler said no need to worry about the loaded adjustment--so I'm interested in best method to get this thing set correctly. Thank you!
