Here is a trick I learned a few months ago to use when needing to rewick or recoil a Kayfun and continue to use the same flavor juice.
Remove the drip tip and place a double thickness of Saran Wrap over the hole in the top cap that the drip tip goes into.
Insert drip tip into top cap, pushing the Saran Wrap in with it to seal off the top of the Kayfun.
Put a small piece of tape over the air intake hole.
Turn the Kayfun upside down and remove the base (chimney should come off with the base).
Set the Kayfun tank, with juice inside, upside down in small glass or container to hold it up right.
Do your rewicking or recoiling as normal.
Remove Kayfun tank from glass, continue to hold upside down and screw on base assembly(make sure chimney is attached first).
While still holding Kayfun upside down, remove drip tip, Saran Wrap and tape from air intake hole.
While still holding Kayfun upside down, place napkin under top cap and blow with mouth into air intake hole a couple of times.
There will be one or two drops of juice that will come out on the napkin.
Turn Kayfun upright, install drip tip, place on mod and vape away.
This works with no flooding at all and after you do it a time or two it is so easy.
Note: Instead of the Saran Wrap you can use a Hillman yellow plastic 5/16 screw protector(H#881039) that can be found in the bolt section at Lowes. A pack of three is less than a dollar.
