Hi All,
  I have a 17Kw Generac Model 0058740,Serial 5872525,running on LP. Pipe line is 3/4" and 10Ft long. It is getting hard to start, then low acceleration and then shut down by under voltage. Its reaching around the 166 Vac range,60 something hertz during the sort time running. Look in the air filter, there is a solenoid working. Its clean. Install a new battery. Thinking of LP restriction, Try with a 20 pounds LP tank and a two stage gas regulator from another 17 Kw that is running well, No difference.
     Is there is a LP filter in the engine gas system? Will appreciate any suggestion. Thank You.

Need to start a new thread instead of climbing on old posts. Have the valves been adjusted? What is gas pressure at static and running? Sounds like a fuel issue.

Check the stepper motor for movement.  The are should go all the way to the left and then swing back to the right as it starts looking down on the motor.
