Just called KB since I’ve had some questions. This is a GEN1 with the breather valve in the snout. They said some ran a catch can but it is not required. If someone is that worried about it they charge $300 to install the newer style snout. But tech support said the most important thing is how it has been cared for and not necessarily which snout it has.
I can send anyone interested videos of the blower spinning. Thanks guys
