My grandpa had fixed up an older lawnmower for me a few years ago. He had done a little tune up on it for me earlier this summer. I had checked the oil in it then and thought everything was fine. Since then I hadn't checked it. Well, i had screwed up the little cable that sets the choke so it wasn't running. My grandpa had it today and said that it had absolutely no oil in it and the engine was knocking. Wouldn't I notice something like that? Looks like I have to buy a new riding lawnmower... My dad is pissed but I guess it is a lesson learned for me since I will be the one to buy the new one. -Travis T.
