Harbor Freight Predator 8750 Watt Open-Frame Inverter Generator Troubleshooting ideas

You should adjust your valves. Had a similar issue with a champion and sportsman unit. the sportsman one actualy showed up as knocking and blowing blue smoke.

All good suggestions and will definitely be checked but how would that affect the tightness of the engine IF the spark plug was removed. There would be no compression and only valve spring pressure and overall friction of pistons and bearing journals.

Isn't it under warranty?? Take it back to HF and complaint loudly.

Good advice. I had an almost New predator engine that I could not pull the crank rope. Just seized up setting for maybe two weeks. I chunked it.

Im surprised it lasted that long. I repair generators for a living, and you would not believe the number of these chepo Chinese generators i see. There also the only small portable units ive encountered that tend to blast houses with uneven power out of outlets. Like 200 volts on one phase and 40 on the other. Nearly every service call ive had involving this kind of damage was due to a predator generatorr.

Mine you , Generac has its issues with high power also. Older 2004-2008 era stabdbys will produce something like 370 volts when the voltage regulator fails. Newer units (2008+) will auto shut down if this happens. The older ones just keep running frying everything in their path. But at least each phase is balanced

I dont know how predators get the uneven phase issues, but ive seen it multiple times over the years.

Gas thank you for that information. I don’t necessarily want any unpredictable voltage on my high priced Chinese appliances. Very useful information
