No extrusion

I have one of the original kickstart filastruders which I upgraded to the v2 parts shortly after they came out.  It's all been working great until recently.  Now it does not extrude at all and I am pretty stumped.  The motor is going strong and the stall board is showing it's going at the proper force.  The auger is spinning and I just cleaned out my nozzle and mesh filter.  I am extruding mg94 abs at 190.  I lubed up the bearings too.  I would like to note that before it got to this point that it has been extruding very slow for the past few months, about 36 hours for 1kg, whereas when I first upgraded to the v2 parts it would take 12 hours.

The only thing I can think of is that maybe the auger/pipe is clogged up and needs a full cleaning?  This seems like the most likely scenario as there was a brief time when I used a different abs plastic when mg94 was hard to come by.

I basically just wanted to see if anyone else had any thoughts before I just take the whole thing apart.
