I really like the stallions, I punch 4 holes 2 bottom, 2 top, then use a fill needle in all the holes to just to poke a hole in the filler material, wicks very good.
Has anyone noticed any primer, the last one I used had it. I noticed the filler was wet after I punched the holes, I put the carto in the tank and filled it, I vapped the primer with the juice. It was a nasty taste for awhile until the primer was gone. I may need to clean the next one somehow before I use it.
