G'day mrkhemlami,
And welcome to our Forums.
I'm not the most experienced in this area, and I'm sure that Max, or Norm et.al. will enhance the advice that I'm about to offer.
But, before you do anything, Remove the rubber grommet from the spark plug completely.
Then disassemble the air filter and give the sponge rubber a good clean and wash it well with De-grease, e,g,
After that, drain out all the petrol, then all the existing oil out of the engine, weather it be by the sump bolt underneath the chassis, or tilt the mower on it's side, using the open oil aperture.
Remove the existing spark plug, note it's number [which will be written on it], and replace it with a new identical one.
Once you've got this far, replace your engine oil, e.g. 30w. 40 or whatever you use, but do not overfill it, as per the dipstick indicator.
Then, once you have done all this, refill your petrol tank, and re-attach the rubber grommet to your newly insatalled plug, give it the customary three push prime, and hopefully you'll be in business.
As I said, there are more qualified mentors here than me, that can help you, but if I was in your position, the above is what I would do,,,
I hope this helps,
Regards,
