It got rid of it to the point I can still see a tiny bit of a line but can't feel it a tall, even with fingernail. Lockwood Aviation did the work, they're one of the authorized Rotax dealers. While I could probably reuse the pistons I have, they have about 70 hours on them and no carbon build up, I'm going to put in the new pistons. They did not need to bore/hone to oversize. I hope this cures my miss and plugs looking oiled.
