Ok, what would you do if your dealer tells you a machine has a 13 horsepower engine on it, it's a Kawasaki so it just has their number on it in cu. in. which didn't mean much to me, I didn't have a conversion chart and he TOLD me it was a 13 hp. I wasn't thrilled with 13, but I knew for a 36" cut it should be ok. We made a deal on it, his shop had totally serviced it but hadn't cleaned it up yet. He was asking $3,500 but I was able to give $3,000. (but I had to "clean it up" It wasn't that dirty, but I still washed it totally, I don't want someone else's grime on it! lol. So I'm going over it and I see the plate that specs the weight, deck size, and horsepower. It says 11! Okaaay... I thought maybe the engine had been replaced... It's an FE-350, which specs out to a 11.1 hp. So I get an 'F' for doing my research I guess... But I never dreamed that the engine horsepower would be misquoted to me! If someone tells you 13 and they sell those machines for a living I tend to think they know their stuff... I guess I forgot to mention, this is the Walker I was looking at last week... Today was the first time I got to see it and I bought it. I did run it around in the lot, I ran it into their lawn and ran the blades on an off several times. It Seems to have plenty of power, but there's no way to test it on real grass! It has 615 hours and is a really clean little machine. But now I'm troubled that this engine is going to be so underpowered... Do I call him on it? If so what do I ask for? I'm sure he'll offer for me to return it and give me a refund, but I wonder if he'd knock off some more on the price instead? I can replace the engine if it goes, that's bound to happen whether it's a 11 or 13hp. I know those smaller engines just don't last the hours the larger twins do.
