Dont get me wrong, its cool.
I got a 800 watt harbor freight generator. Its a 2 stroker. Guess what? Even if it goes 5 hours on a gallon of gas under light load it skips combustion cycles blowing raw fuel and air out the exhaust.
Its got a real neat sound for full load vs partial as it runs the same rpms because its a generator.
PS, Our dog got the cooking mistakes, old food, stuff we were sure if we should eat from the fridge. Many times this was fast food that was put up for a few days with lots of gravy, butter, fat, etc. Boy our dog loved that vs dog food. One day we had dresses some meat cutting off lbs of fat. He got that to eat and was jumping 4 ft in the air for joy.
