Lawn mower engine running unevenly

Hi All,A quick update on my mower - thought I would start a new thread in case the specifics helps someone else in the future The mower started first time - I was amazed. However... The engine runs very unevenly. It doesn't sound like it is likely to stall but runs what I would call lumpy with an uneven rev. As advised here, I did the following before firing it up...1. Checked the plug. It was clean with no residue. I checked the gap and it was about 21 thousandths inch. The manual says either 20 or 30 but I can't tell which one I have to know for sure2. The air filter is mostly spotlessly clean but a little but of what looks like oil on the inlet side where the holes of the casing are3. The petrol tank had a tiny bit of fuel left in it (not enough to pump with the priming bulb) so have put fresh fuel in with the dribble that was there4. No smoke seen of any colour or noticeable smellAnyone have any idea where I should go from here?ThanksLee.

Quick update. I managed to mow the lawn over the weekend including an area of long (say 6") densely populated grass without any troubles. So based on the various feedback here thing I should leave the mower as is.

Thanks for all your help

Lee.
