My flooding issues were over,once I started to make my coils,and wick larger! I use a small screwdriver shank,(3.4mm) to wind my coils on. Then I make the wick, large enough that it pulls through the coil,with a lot of tension,but not enough to move the coils out of position. Then I cut the wick tails about a 1/16 inch longer than the RBA sides,and push it down inside the RBA gently. I also make "small" channles in the wick tails,where you can just see a small portion of the juice channles openings. I think some people make the area above the juice channles too big,and it causes flooding? I've used 50/50,40/60,and 30/70 juice in the tank with no dry hits,or leaking.
