This looks exactly like my engine did.

I think you have 2 options.

1) Ignore it - it's how the engine runs ex-factory.
2) Take it to a good dyno tuner who will tune each cylinder to perfection.

OK there is a number three

3) Spend hours and hours doing it yourself with TuneECU.

To remove the carbon buildup in the exhaust chamber, get a spray bottle with water. Rev the motor just a little over idle, and spray a little water into the intake until the motor stumbles a bit. Watch the black smoke blow out of the exhaust. Repeat until the smoke comes out white.

if I sensed everything it should be done so..

therefore while it's obviously on neuter I dle within 900-1000rpm ..
so nebulize not distilled liquid in injectors until it grumble ending with stumble too.. of course not excessively in terms of both noise nor briefly so nor of time.. whereby I must do it until blow out only white smoke without presence of soot..

That sounds right. It steam cleans everything.

I wouldn't do it so like you suggest, therefore with hot liquid nebulized, for I don't own object with which to do so.. thus I would do it with wrist nebulizer, so with much less degress of hot, though I would use only undistilled liquid..

That's exactly what I was talking about. The water gets heated in the combustion chamber and cleans everything in the cylinder and exhaust.

so I'm not worried, it's nothing serious so.. I didn't perceive correctly, otherwise correct me.. I'd let it go if there's no risk of costly consequences.. so I would rule out going to someone.. for everyone believes to be the most competent while very ofen it's the opposite..
