Drigging oil from burner

[Lincoln22]

Camray 5 (90A) (20 year old) oil boiler, had a noisy fan on the boiler so investigated, just a bit of dirt in the casing however, having removed the burner unit I replaced the Burner Nozzle no problem, old was very dirty and sooty. Found the boiler wouldn't fire up. SO rather than than mess around buying piece buy piece I replaced the, capacitor, and Needle Valve Solenoid, no luck, changed the "magic eye" and boiler fired ok but smell of oil remained. Removed the burner unit again, found oil leaking (running) out of the burner nozzle so replaced the Needle Valve. No luck, oil still running out of the burner nozzle when boiler off and just oil supply turned on. I'm all out of ideas, any help appreciated please.

You refer to luck, here is your problem. Get someone in who knows what they are looking at. It’s not luck if you understand the boiler and know what’s working and what isn’t.
It is luck if you just chuck parts at it until it works, also usually expensive and wasteful of resources.

As above stop wasting time/money and get a competent oil engineer.
If nothing else you cannot make any meaningful adjustments to the burner without test/analysis equipment.

With no pressure gauge or flue gas analyser and the competence to use them you're piddling money away.

It would have been far easier and cheaper to get somebody in as said above.

It's getting cold out there ⛄⛄⛄⛄
