I wouldnt say most are two stroke. In fact most mowers available for purchase at your local hardware store are going to be 4 stroke if not all of them. 2 stroke lawnmowers are a thing of the past. Everyone wants 4 stroke and self propelling now.
I consider lemmy in different realm of social media. The people here are not at all like the people I meet irl where I live. If I ever met someone from my small town who even knew what lemmy was id shit myself.
