Have you tried working the hot spot out? Just gently prod the top coil while pulsing your battery and it should let the rest of the coils glow. Make sure to do this with an empty tank.
push wick towards center post, that top coil is too snug against the wick.
Are you wrapping in situ or using Drill bit/ PetarK method?
What is the resistance reading on the coil in the picture?
My wood swells.
top hot spot was always my nemesis... always.
1. pulsing short bursts, over and over... after a good doz. bursts, gradually increase time...
2. take a screw driver head (flat) and push or indent the top wire towards the inside of wick, giving more coverage to wick
3. try the cheesecloth thread trick... it ALWAYS works for me... (natural unbleached cheesecloth; 1 strand about 10" long... wrap it around the coil where the wire (coil) will go and wrap your wire over it... use a drop of juice to "glue" the thread to the wick... porous ceramic works best but ss mesh is fine.
