IF it has a poor draw you could try a number of things -

Cut more of the head off (could cause wrapper to unravel)

Roll the cigar btw your fingers to loosen tobacco and identify hard spots

Stick it right down the middle (through the head) with any regular BBQ skewer, I bought some stainless steel skewers. Don't worry about the size being too big, it's fine. Just don't poke thru the wrapper, keep a straight line. I've heard that dryboxing for a day or two sometimes helps.

Try the first two suggestions first, sometimes cigars have hard spots they just have to burn through.
