It does fine when you first crank it. Once it warms up it surges back and fourth. I took the carb apart and it looked ok. Put it back together same problem. The only time it does not surge is when it has a full load on it. Any help would be appreciated thanks.
I had a Colman that only surged when it had a large load on it. ConsumerReports.org says that some Coleman generators just can't hold a constant voltage. Hondas are expensive but very good,.
Re. Coleman Powermate 5000 Watt Generator (surging)
Apparently, no one has a solution for this. I have been fighting this "piece" of equipment since the day I bought it. At first I had to spray gas into it to even get it started. After a new carburator, valve job, spark plug, new head head gasket, and new governor spring, it now starts after a couple pulls but still surges terribley. I am at my witts end and refuse to put more money into it. It's only good enough to run a couple of lights, just can't trust it to run and or ruin a refridgerator. Sadly disappointed in this so called generator.
