Long story short, I ran into a buddy who was needing some money. He had a YTH21k46 for $450. I've been in the market for a rider so I jumped on it. It runs real well the only thing wrong with it is the ignitin switch is a little loose and the key is stuck in it. Sooo, I got online and ordered a switch (still can't find a new key) and then I decided to do a little research on it. He said it was about two yrs. old and the display shows 87 hrs. I find this site only to discover that this is the worst engine ever built. Can I expect to get a couple summers out of it or did I totally waste my money?
