Expected a slow day watching fire in the furnace, not going to happen. Decided to try the atmospheric burner in the morning heat. It lit but insisted on burning well down the pipe. No adjustments I made would get it out of the pipe. Tried it on the vise, good there. Removed Asian welded burner pipe and filed down the weld ridge down the middle of the pipe, tried in furnace, no go

.Because of furnace back pressure the venturi effect of the reducer was not generating enough velocity to overcome the flame advance. My jet was 3/4" from pipe inlet, Rupert Wenig's was 5/8" but some of R. Reil's were as much as the full length of the reducer 1 3/4"

. I removed the T and jet and went with a straight pipe with a #53 jet drilled in it. After some fiddling to center it down the burner pipe, distance to burner pipe now 1 1/4". Lit on first try and did not retreat into the pipe as I ramped it up.

Installed 2 grease fittings on the main lift slides.
The rest of the pictures are my evening heat with the atmospheric burner. Moisture is all gone, developed a few small cracks. If or as they get worse an occasional application of vesuvious should keep it in repair. Included the second last pic. just for the rich color. This was just before I shut it down.
