Their are numerous ways to "build" for a kayfun so each of us has to find our way for a repeatable and reliable way to build. My own experience and all the threads I have read lead me to suspect a wicking issue to fix most of the problems you may have. Here is a pic I did for a friend and although it's not the only way to create a build it helps me explain in pic numbers 4,5, and 6 how important the length of the wick is.

Too long or to short often causes problems. To much or to little also causes problems. Also, in pic 6, I install the chimney after the wick is cut and saturated with juice. I prefer this way as opposed to threading the wick up through the chimney and then cutting it.

In the above pic Before Clean shows you what a Bio Wick Organic cotton wick looks like after some use with a fairly gunky juice. I clean everything with Wallgreens house brand Denture Cleaner which does a dandy job, is cheap, easy to use, and delivered in discrete packets. The After Clean image on the right shows you what the results are for a 20 minute soak and pre wash and after wash procedure. In this case I removed the cotton wick, dry burned the coil, and then installed a new Bio Wick organic cotton wick. In a pinch, the wick is clean enough to continue to use after the clean (No new wick) if my situation called for it.

The above pic shows how I prepare Bio Wick on a KF. It starts with a rough cut which is the pic on the left. Note in this pic that the wick is to long but remember it's a rough cut and not the final cut. Next I saturate and I due mean saturate the wick with juice which is the pic on the right. I wasn't quite finished saturating the wick when I took the pic. I press the wick against the ledge as I saturate it. Take your time and do not perform your final cut until the wick is fully saturated and kinda flops against the back of the ledge.
