Gererac ,hard starting
I have a 20KW,2 cylinder,Natural gas generator that goes thru 2 long cranking start sequences before finally starting.I have kept up regular service per the manufacturer,plugs, oil,filters,valve clearance,etc. With air filter cover off, & watching while its trying to start,I noticed that the choke disc on 1 of the 2 venturis initially closes then opens,then closes again.Is that normal ?Shouldn't it stay closed until start up ? It does eventually start after 2 long cranking sequences. Is there a way to adjust how long the choke stays closed ? Some dip switches or something controlling the choke solenoid ? Any idea's would be appreciated. Thanks, Sgt. Rudz.
