If a engine comes defective from a factory it should be replaced, no matter what engine it is or who makes it! Bottom line!
Is this pict old news?

I talked to Horizon yesterday about my .82. First, they found the piston was chipped just under the ring. I don't know how that happened, and I'm not sure I like the thought that a piece of aluminum was bouncing around the inside of my engine. Then again, it could have come from the factory like that and nothing at all was in my engine. So, I'm guessing they replaced the piston. Hopefully they replaced the ring as well. As far as the valve leak goes, the tech who was working on my engine told me that he polished up the valves and they were now sealing perfectly. The valve seats were fine and he did not do anything to them. I'd prefer the engine have been replaced, due to the chip in the piston, but the guy said he found no other damage in the engine at all.
It was all covered under warranty.
Hopefully when I get it back there won't be any problems.
