Thanks Cub48. I think I was just really frustrated. I bought the separate heater and that helps with clogging, but I was getting a lot of air. Probably caused by what you were saying. I have the newer model with the brackets which is nice. I like the idea of blowing out the channels, I'll have to try that. But yea the center block doesn't get nearly hot enough. I'll keep trying.
thanks again
Chad
