I am no expert at all but I would try a hotter burning wick,that may also help with the scent throw.Maybe htp wicks ,#126 .Eco seem to burn hot in My 4627 candles but I find they may smoke in the beginning,not my favorite wick.Other candle makers may chime in to help you more.I use a jar 3 inch wide by 3 inches and lx 16 works great.zinc 51 works well but the mushrooms just kills me! I do like htp 93 or up 104 ( jar gets hot with 104) wicks for heavier scents.Maybe that would help you.Don't forget to stir gently, blend your scent well.Try a different scent,not all scents work well in all waxes even 4627.Have fun.
