The reason I'm asking is because I can't find the thread. It refers to the little vents down at the bottom of my burn pot in my harman p68. Someone suggested to clean these to help with build up on the flame guide. Long story short, a HUGE thank you to the poster because I used this tip and after a week I have ZERO carbon build up on my flame guide and was accumulating buildup after a half a day. Poster, please stand up and receive my gratitude!
