How to adjust oil furnace electrodes and flame?

Thanks, Mike.
I'll try setting the electrodes flush with the plane of the nozzle like it
recommends, the rest of the system seems OK.

That's called a "tagline", young man. If you've been on Usenet for any
length of time, you would know what that is.
And I may not know every little detail about tuning a furnace, but I've got
the safety aspects covered pretty well, and if I'm as stupid as you and a
couple of the other trolls here think I am, then you're just simply going to
have to come over and personally show me how to set myself on fire. Unless
you're a pussy....

You missed the simple fact that properly adjusted oil furnaces don't soot
up. If it soots up, there is too much oil and not enough air.... the oil
companies don't care about you having a properly burning furnace, they only
care about selling oil.

Now... spend a few bucks and call a *REAL* oil tech and have it done right.

Sounds like you have too much oil flow or not enough air flow...

Are you sure the old nozzle was 1.35 gal per hour and not less?

Did you mess with the pressure regulator?

Is something clogging up the air flow?

Also some burners have two sets of air bands, on is a coarse
adjustment and one is a fine adjustment?

I didn't touch the fuel pressure regulator screw, I already know from what
I've read on the web that that's a big no-no without having the proper
meter. The fuel nozzle is definitely the same as what was previously on
there (I had also tried a smaller nozzle that's 1.00 GPM, and it's just as
smoky). I had cleaned out whole the air intake last year and it's still
clear now. There isn't a fine adjustment anywhere, just the big collar on
the left of the motor.
