Yep. Grew up with my grandfather working on small engines (read:lawnmowers, either push or driven) and one of things he would do when doing maintenance on them was to sharpen the blades with an angle grinder. Mades mowing a lot easier and generally looks more uniform as well. The other thing was that it almost always is the carb if the engine has issues.
And next thing you know it’s the next morning. Which is why I don’t play factorio too often.
