Maybe you are building to small of coils. 30 gauge at 7 wraps and mine come out to 1.9 amps. Stuff with organic cotton and finger nail clipper cut as close to head as possible. Then lay on top 2 strands of silica wick and snap on chimney and then clip silica. Have rebuilt 50 0r 60 and have had only one bad one. That one had to much cotton and it was like sucking a golf ball through a straw.
