I would say that if it runs lean...there is too little fuel in mixture?
Typo?
I would rather describe that sound as sound you can hear when you turn on a electric coffe grinder...and that sound is sound of death
Depends.
If referring solely to stoichiometric ratios (air-fuel), yes.
If referring to 2-cycle mixes, too lean means popping noises with too much fuel and not enough oil. Rich means too much oil and not enough fuel with visible smoke from the exhaust.
Another way to describe the "high-pitched popping noise (short explosive sounds)" is the sounds a Kurig coffee maker sounds when the last drops come out.
