Hi folks,
I have an old cast iron boiler that used to burn coal back in the 1940's,
and had been converted over to heating oil. It uses a pretty standard
looking 3450 motor that's about 30 years old, and I clean and maintain the
boiler myself (a pretty damn messy job, I know). The only problem is, I'm
not sure how to properly adjust the ignition electrodes. I just vacuumed out
the boiler, replaced the oil filter, and then replaced the fuel nozzle with
exactly the same kind that it was using before (60 degrees spray angle, 1.35
gallons per hour flow rate). The problem is that even when I open the air
intake band all the way, the flame is still long, red and smoky. I tried
another new fuel nozzle with the same results, so I'm pretty sure that the
nozzle isn't clogged up. I'm guessing it has something to do with the
position of the ignition electrodes possibly interfering with the fuel spray
pattern, and I suppose I could go back and forth about a hundred times
disassembling and reassembling the fuel gun assembly until I get the
electrodes perfect, but if anybody out there can give me the proper
specifications I would very much appreciate it (there is no specs label on
this motor, I checked).
Also, can anybody give me some tips on adjusting the flame? I have some
general idea that the flame should be made as big as possible, without
giving off any smoke or long red "fingers". When I adjusted it last year,
the furnace seemed to run pretty efficiently and there wasn't much soot in
it when I cleaned it out, but it would be great if anybody could give me any
tips on this.
Thanks in advance :-)

If it was working right it wouldn't be. you either have
excess soot, or excess unburned oil, and neither is good. A well
tuned oil fired boiler burns CLEAN.

You don't touch them. You have neither the tools nor the
knowhow.

I dunno - throw a few more nozzles at it and see what happens.
Try some different ones. Whatever Home Depot has in stock that day
will do.

Call someone who knows WTF they're doing. PAY them to come do it.

Here's a good write-up on tuning up oil burners and adjusting
electrodes.
