ive really only used boge up til now. ive got some iken 510 gold cartos and i notice when i take off the little white plug there is a silicone plug under it next to the batting. why is this there? i removed it to fill the carto then replaced it and popped on a drip tip. the draw is good but kinda stiff. should i just remove the silicone piece too?
is this silicone piece in the fusion too?
