onan 7000 marquis

My Onan 7000 will not run both A/C units without serging, rpm goes up and down continually. The unit was fine last use about a month ago but now has developed this problem. Any ideas would help.

RE: onan 7000 marquis

when was the last time it was serviced???
The way it sounds is that the governer may be sticking or u may have a lean fuel condition,, imo i would ck all the filters and ck to make sure u have enough air flow to the unit.. i would also ck the fuel ,, u may have a bad batch,, does it do it with only one a/c running and all other ac appliances running or just with the 2 a/c units,,, ????
