It can take a while to "bed in"
Or the coil might be a bit tight, try wrapping the coil round the wick and a paper clip or a needle, then remove paper clip, this should give the wick some breathing space, also I flame the wick til it glows, as it helps with the bedding in period, you can also flame the kanthal wire before you wrap as it takes the springness out of the wire
Thanks guys, just ordered some nichrome wire .2 and some more wick. Trial and error i suppose. Hopefully next rebuild will be better, :-)
