I recently replaced the stem (middle piece thingy) and bowl of my shisha and put it in my old baseThe smoke is a lot thicker now but when I draw from it, it's very slow and hard to get a decent pull (it's pretty taxing on my lungs)What can I do to fix this?P.SThe new bowl is quite a bit bigger than my old one so maybe it has something to do with the number/spacing of the holes I poke in the foil?Thanks
