I am working on my burnham woodlander mfb 301. wood on one side oil on other
i am havining an issue with the oil burner. its been stumbling, coughing from time to time. sometimes it keeps running sometimes it trips the lockout. I have changed everything. I have searched everywhere. im about to call a tech! help me lol
carlin 100 crd burner
new filter, screen, nozzel.
elecrodes not new but right where they should be with a good gap
transformer good spark
the oil has been treated for cold weather by me...
the oil line is a single line, runs about 70 ft with the burner being about 7 feet lower than the top of the tank
line has several couplings, all are tight and show no signs of leaking
nozzel is the manufacturers recommended
burner air open 100% as per factory setting
nice flame when its running, no sooting at all

Check the coupling between the motor and pump. A little age and or oil and they give up. It may start and run fine for a bit and then give up. Most are just a tube with a rubber washer on each end. Cheap but a little oil or it dries out and it slips. The fan will run but the pump gives up once the resistance increases.

Put a pressure gauge on the pump (a 100# should do it), there should be a pipe plug on the top for this. It may be a square head or an allen socket plug. If the pump starts to lose pressue just before it quits, it is the coupling. Being fairly old and sitting a lot doesn't help them.

so I havnt had any issues the last 2 days. I tried tightening all my couplings on my oil line they all tightened a little-nothing I would consider an air leak but so far so good. I put a pressure gauge on the pump and it is pegged at 140 when running. idk, fingers crossed

Burner air open 100 percent does not seem right and could be a cause of the problem. 140 pounds pressure is too high, it is over firing.

has been running perfectly, perhaps it was air in the lines.
