TRY THE VIDEO ON RIP TRIPPER , IT SOLVED ALL THE ISSUES ON MY LEMOI give up with this tank. Tried normal and spaced coils at 2.5 and 3mm. I've tried jap cotton and rayon. I've tried 3 different size pancake wicks and about 5 different size normal wick ranging from just touching the deck to filling the deck and just leaving the juice channel open. Convinced it's something with the vacuum not working. Sometimes I get through half a tank before the dry hits start, other times its every 3 or 4 hits and I have to keep priming it by blocking the air holes and suckling. Not sure if mine is defective or what. Dont even want to put it on the classifieds cause I don't want anyone else to have to deal with this POS.
