When I get a pipe that won’t burn I just light it up every puff. Sometimes they be stubborn. If it burns in a cigarette it should burn in a pipe though.
try to make sure you load it up even. Sounds silly but when I push it down a little while loading it I give my pinky a twist. To try to kinda twist it all together.
when you light it I kinda pufffff puffff puffff pufff like to try to get full ignition if that makes sense. Lol it’s different but when the weather is *s-word out I can smoke on a pipe and just take a few pulls vs a cigar where you’re looking at a minimum 30 minutes on a small smoke.
