I always used needles, including bent one for wall holes.
I guess, this is a wrong way?

Anything that fits the orifice should suffice, but it should be a softer metal than the brass jet. I've used torch tip cleaners personally, then high pressure air, after using carb cleaner.

 

[Intruder8]

I tried a wire from wire brush, nothing works for me but needle. Deposits are too hard for a soft wire, sometimes needle cannot go thru.

 

[CRracer712]

You need to soak them in carb cleaner first.

 

[Intruder8]

how long?

 

[CRracer712]

That depends on how dirty they are.

Overnight is a good starting point

 

[CRracer712]

Overnight in Alaska, or Kansas? And what time of year, cause nights are longer in winter.

 

[Intruder8]

Maybe boiling can soften deposits? Who tried? I don't have patience to wait overnight.

 

[CRracer712]

Go for it. You've got nothing to lose at this point.
