I think you may be looking at the normal operating temp that you are going to see. The coolant won't boil until about 220. I would put in infrared temp gun on the engine, specifically target the metal neck where the coolant hose exits the engine. The infrared reading will tell you how accurate the gauge is. Also the control system on the generator has an internal circuit that will shut it down if it overheats.
