Customer Question

We have a QSX 15 in 500 kVA generator application. Engine has hard starting and blows excessive white smoke (a lot ?) when idling at 1500 rpm. Funny thing is that as soon as we apply load, the white smoke ceases and the engine runs normally.
What could that be. We have changed the actuators and checked injector torque values, seem to be ok. What could it be ?
