Dont feel bad. I had a all gas weed eater with the swappable attachments and everything. Thing always ran good, plenty of power and torque. Last summer I crank it and go out and start buzzing the walk. Well, about ten minutes in it acts like its out of fuel. I check the gas. Plenty of gas. I pulled the cord and it starts up. Acts like its loaded up and then within a few minutes shutsdown. I give up thinking its maintenance time. The next weekend comes and experience the same thing. After three weekends, I start getting antcy....I am in the garage and find this huge puddle of oil. I star cleaning up and the youngest comes by and says "Oh Jasmine and I needed some oil for our skate boards so I unscrewed that plug and oil poured out. I did not want to make you mad so I did not tell you." I unscrewed the plug and the crankcasae was essentially bone dry. Fortunately I had treated that engine with Lucas oil treatment which penetrates metal. I think thats what saved me. The weedeater still works today, just as well as it used to.
