They are nice. Tricks for the kayfuns. Don't stuff to much wick in the wick trays, filling from the top will likely cause the wick to be flooded for a brief time, DUAL
coils rock (see shotgun
coils video) and Cotton IMO is the best wick but remember in cotton less is more don't stuff it in the coil, very lose cotton wicks better. Like all RBA's work over a table or you will likely lose a screw carpet is the enemy. If you ever need a new screw or insulator go to Fat daddies web site. I broke the center post screw LOL OH make sure you have a good seal between the chimney and the top of the kayfun our you well have a leak.
