I have the nozzle out. And as I mentioned there, may be time to replace the brass pipe, teflon tube and peek.
Well....to give some follow up...I used a candle to loosen and get some of the carbon fiber filament out. But...that also generated a fair amount of soot. (Regular, unscented candle)
I re-installed the nozzle into the print head (just a few turns, left in loose) and heated to 180C. I also tightened the brass tube into the heater block, it had become loose...once that was tight, I tightened the nozzle in. Then, at 220C i started doing atomic pulls with PLA filament(bowden tube removed). The first 4 or 5...heat to 220C, then set to 90C...then tug filament out....generated good "popping" sounds and soot. Finally, around the 8th time, I was able to press in the PLA and see filament squirt out the nozzle.
Phew, not a fun time but all back together again and printing

I usually first just purge the hotend with pla, then when the pla starts to exit almost clean, then I do atomics. Can you extrude anything or it's totally clogged?
