From my understanding the lemo deck is a bigger version of a kayfun deck. I don't have the lemo yet but plan on getting one! I would apply the same principals with wicking. I do the bunny ear deal.
Wick the coil, put on the first section of the chimney, cut slightly above the top, remove the section of chimney, wet the wicks and gently push them down to the deck. Reinstall the first part of the chimney, looking down thru that section, make sure you still have the deck covered by the wick as sometes when you screw on that first section of the chimney, you have a tendency to slightly move the wick. Just readjust the wick so you have total coverage across the deck again but not jamming it down to pack the wick onto the deck.
Those little things have helped me get a consistant build on my kayfun and should work with the lemo as well I would think!
Not into the juice channels, just total coverage across the deck. Just trying to figure out how your juice is leaking and this is what I could think it might be!
