that pipe is no longer any good! you should put it in a box and ship it to me for proper disposal. seriously though, just needs a good cleaning. put it in a disposable cup, fill with isopropyl alcohol and let it soak for a good long while.
how'd it stop working? like, was it fine when you put it away and when you took it out at a later date it was blocked or did this happen in the middle of a sesh? can you see anything? was the pipe dropped any time before the blockage? can you blow through the pipe in reverse (with the carb covered?) take a pen apart and use the ink tube as a poker. theyre strong yet fairly flexible. just dont get carried away. even better if you have an "antenna tube" from a radio controlled car/truck good luck
well its quite simple. something is blocking air from coming thru the bowl. its really not that hard to get it unclgged. when resin heats up it melts. heat up a paper clip. or light it like your lighting a bowl and suck hard. be a man lol
Put some water in it through the crab then blow in to it while holding the crab if done right water will unclog it. But put your hand over the bowl so water doesn't go every where.
I would suggest not inhaling hot resin Like someone else said already, get alcohol and salt. You could also try running hot water on/through it as best you can first, to loosen it up. The alcohol will dissolve the resin, the salt will scrape it away. You can also soak the piece in alcohol for a bit to try to get it to break up the crap inside.
