(EDIT POST UP DATE)
SO AFTER ABIT OF TRIAL AND ERROR AND GOD ADVICE (DONT DO IT THIS WAY !!)
USE A SYRINGE AS EVERY ONE IS SAYING!!!
IM ONLY A NOOB AT THIS !!
see video page 2
why have i not seen this filling style before its GOLD
no more driping in the carto for me ,this is fast easy hardly any mess and last twice as long with more fill
im even doing the new Smilomizers the same way
just make sure you sit them and CLEAN the treads
( !!!!!THE BAD WAY TO DO IT !!!!)
Still works if you do it right though
Also a way to recycle the liquid from an old carto to a new one
