Get a Chinese Powertorque and mission accomplished!
I wonder if they still make them over there? Maybe some Chinese mower company might be manufacturing power torques as we speak (well, shutdown for the corona virus, but still). I am pretty sure they make a knockoff suzuki 2 stroke engine, or something very similar. I remember Masports had a 2 stroke for a little while, with something that looked like one of the suzukis stuck on it.
