Pellet flavour is ok. And there is next to no ash in firepot after cook.
That's the general feedback....
if it's the Pellets I will come back to you on here.
Don't personally think it's the pellets Jimmy70 ....and the length should not matter as the auger will break them up...they are not a hard pellet to break down by any means and your auger should cope with the length IMO.
Jimmy70 you should also reach out to Rod Duggan on FB about your issue as this is the first time I have known anyone to be having issues.
Or give him a call...will send you his #
