What do you guys think of this deal......I would use it in conjunction with my Navigator...and only on smaller lawns. 1996 walker (mc?). I think it has the 16hp, it burns 1/2qt every ~5hrs. Other than that it looks like it is in real nice shape. newer seat too. Around 600hrs on it. Wants 2200 for it. I am gonna use it in the morning. Do you think it sounds like a fair deal? Thanks in advance.
