I forgot about the boost port. I'm surprised it ran at all.
Don't feel bad. I shattered my rings after a week. My kit was a lot more than yours. It happens. If you didn't score the cylinder up too bad you're lucky. I was not so lucky. Take your time. Soak the piston, rings, and pin overnight in 2t oil. And for gods sake, make sure you're not running lean. Change the main jet right away. That will kill a piston and rings real quick.
