how to smoke resin out of a bubbler?

all the resin is building in the stem and thats hard to get out. i tried holding lighter and matches really close and sucking, but i dont think im getting anything cuz no smoke is coming out of my mouth. any suggestions?

im weedless right now im desperate haha

p.s. it worked better when i used matches but im not sure if thats resin or match smoke that was just in my lungs =/
