the juice falls right through the ones that don't work. It's getting in everywhere BUT the coil area, thats the weirdness.
I took one of them apart....the filler was loaded with juice.
If it was too thick it wouldn't pass right through would it?
The juice I've mentioned is used by other gogo users with no problems.
Have you tried pushing the filler down with a soda straw.
I know of one user getting over 4 months on a go-go carto using madvapes bavarin fudge creme.
