Since we've lived here, I've learned how to drain the oil, add the correct amount of oil and clean the air filter! I'm sure more is coming. I'm starting to recognize little symptoms of the lawn mower by how it sounds, like when it doesn't have enough oil and when it's flooded. I guess you can't really know too much about stuff, but right now, I smell like gas and oil - kinda' reminds me of how my Dad smells after he's been working on some mechanical thing - minus the extreme sweat!
It may not sound like much, but I'm pretty proud of me.
