I know with Composites there is some possible causes. Remember that the series field of those Dover generators are sometimes touchy during the change of seasons. You can adjust 2lr on the leveling ring to advance or retard that leveling step and sometimes gain control just a little longer if your coming in a little hot. That MG is a bucket of energy and by the time your floor level, you have to dump it all out. slowdowns, and resistor taps. You can move 2lr and many times fix it. (for now)
