is One Chatty Farker
I have a 500, and had 1 small episode of back burn due to a collection of dust in the bottom of the hopper. I've found that before every long session, I take my Shop Vac and vacuum out the fire pots, then I vacuum the hopper / auger from the firebox side. It sucks out a bunch of the fines / dust. Since then, no problem. Knock on wood.
