Hey Russ- did u have build up on the back of the chamber like last time?? How many gallons of oil did it take to get your build up?
When i was playing with my burner last winter, i was getting build up on the back. It would grow out about 2-3 inches. it took about 15gallons to get it there. I bought an eco-nozzle and put it on my new tip and absolutley no build up. I have run about 75 gallons through it and i havn't had to clean it at all. It seems to start a tad better too. I have general ash and soot in the whole chamber, but no growth off the wall towards the nozzle. oil temp is 225, pressure is 130, .75 80degree tip. I also am trying a 90degree tip now and i'm having better starting with it, and seems like its lasting longer!
