James,
I re-read my comment, and in hindsight, I shouldn't have even commented. I probably came across as being offensive. My apologies.
I, nor any of the folks in this area have any issues with our units, other than updating door gaskets and replacing nozzles. Both are wear items, and we knew that going into our purchases. We all have about an eighth inch of creosote in the bottom of our airboxes, but it doesn't appear to be getting any worse, so we don't even bother to clean it out. The firebricks broke on our secondary burn chambers right away, but a call into Rory @ P&M netted us all with new shields to replace them, as well as new rear covers for the air boxes(two of us have not replaced ours yet). We do go against what P&M says where our nozzles are concerned. We do poke them out(with the opposite end of our hoes that came with the unit) every time we load, knowing that we could potentially chip fragments out of them. These units are no different than any other gasser out there, in that they do not function to their potential with plugged/partially plugged nozzles.
I've not been in your shoes, so there's no possible way I can understand the frustrations you are experiencing. I owned an Empyre Pro Series 100 before I bought my 250, so the learning curve for me was not as steep as yours. My experience also helped the others in this area.
I always reply to any pm's sent to me, James. I've probably even talked(phone calls) to a dozen or so 250 owners, a few CB gasser owners, and even a GT-220 owner.
You got me thinking now, have you and I ever talked?
