I'd bet this car engine will be lightly loaded since it's many times bigger than the engine in a generator. From what I was able to dig up[1][2], the generator (that the alternator came out of) has a 1-cylinder, 4-stroke, air-cooled, 305cc engine. A Toyota Sienna minivan's[3] engine is around 3L, so it's basically 10 times as big. --- [1] generator product listing: https://www.lowes.com/pd/Troy-Bilt-5-500-Running-Watts-Portable-Generator-with-Briggs-Stratton-Engine/4764073 https://www.lowes.com/pd/Troy-Bilt-5-500-Running-Watts-Porta...
