I have installed a Briggs and Stratton 12kw lpg/ng generator it runs rough and is putting out 45 volts to ground and 88 volts phase to phase , it's supplied with a portable propane tank , inlet on generator is 3/4" supply from tank is 1/4" ? Maybe problem ? It also seems to be letting in gas when not running ? There is no harness to connect on this generator and I have correctly turned set screws on carne raptor several times ? Not sure what else to try ?

Got generator to run by increasing propane supply line and voltage is up at normal , only problem is propane continues to pour into carberator even when generator is not running ? I have the same problem with other generator ( same model ) that I installed . Shouldn't controlled regulator close valve ?

Yes, the shut off solenoid should stop the gas flow when the unit is not running.
