Disassembled printing unit - something jammed inside

I have disassembled my k1 Max nozzle, fan and extruder assembly. When I stick the long tool into the hole where the filament should descend it is not going all the way through. I cannot insert it through from the bottom or through from the top. Is the tool supposed to be obstructed when pushed through either end of the printing head assembly I disassembled?

Is there an obstruction I have to clear?

I am thinking of getting a small torch to heat up the end of the pin tool and stick it into the hole to melt out a piece of filament jammed in there.

Any suggestions?

If you only have the nozzle removed from the hotend assembly you can heat up the hotend and then clear the blockage.
