I have a 2002 Polaris 600 VES motor. I just recently took out the Power Valves off the top of the head or the little black diamond looking thinks just in front of the head. When I took these out I forgot to mark what is the correct way to put them back in and also what the spec is on them when you push them in. Is the number on the valve suppose to face the sky? Or the Ground? Also what is the setting if you push the valve in with your hand? Should there be a gap or should it just flush up with the end of the valve if you push it in with your hand. I did not know that rotating these would change the setting of them. Any help would be fantastic. Thanks so much guys
