Race,

It's not like I make it a habit of buying used engines, but if I do, I try to do my homework before I buy. Like I said in my initial post, the engine appears to have never been run. I'm just trying to make sure I break in the engine the way it's supposed to be. I've never had any experience with Mecoa. I have bought several used engines in the past, and all have ran perfectly, but it's like I said before, I try to do my homework before buying. In fact, out of all of the numerous new engines I've bought in the past, I've never had to warranty one. Evidently I'm doing something right. Anyway, to go against what you stated, there is nothing wrong with buying a used engine without a warranty as long as you check it out thouroughly before buying it, even if it means running it before buying. And sometimes, you may get a heap of crap you can do nothing with. It's not a complete gamble though.
