Generators require professional maintenance. They are not lawnmowers. Yes, they have an engine. The difference is…instead of turning a cutting blade, they are turning a rotor. The rotor rotates courtesy of the turning crankshaft of an internal combustion engine. That engine must be precisely tuned to a much greater degree than a lawn mower, or your cars engine. The difference is that the rotary cutting blade of a mower, or the drive shaft of your car will turn, in spite of a poorly tuned engine. Yes, they will still function, albeit poorly. The efficiency of the engine governs the efficiency of the vehicle or mower. Poor efficiency will result in poor fuel economy. Poor performance. Generators are a far different story. The engine must be finely tuned because it must turn the rotor at the precise RPM.
