Ok so I took the piston pump off, got rid of the 3 coils of 1/4 copper tubing that go around the burner for pre heating. AND IT WORKS now.....for tuning I've got to figure something out.
Im running 60PSI air and it smokes like a mad man.
Mine is in a 55 gallon drum on its side

If I plug off the 2" bung on the drum that you usually would access the contents through it chokes out the fire. If I leave it open I have a solid stream of grey/white smoke billowing out of it. Along with the 6" stack on the top is billowing smoke out of it.
I understand the flame needs oxygen to an extent to feed the fire. How is everyone feeding the fire? Do you have a fan blowing into the combustion area some how?
