Not sure how many visit the Factory Five sites, but this was posted today. It's the first issue I've seen on these engines.

That definitely looks like a flawed casting.

I follow a lot of Coyote sites and have not heard anything regarding this issue...but I passed on the link to Bob Monks for his input.

I also forwarded to Alex Flores for his review.
