Hi Blink,
e-liquid is not suppose to have a high viscosity. You need to cut that e-liquid with wither thinned out VG, straight PG, pure grain alcohol, or distilled water. Otherwise it will not wick properly and possibly clog your atomizer. Remember that diluting it will lower the nicotine content slightly and it only takes a little of and of the above listed to thin it out to a proper viscosity.
Hope that helps,
Sun
