This leaves in rich air fuel mixture. 15:1 means that 15 parts of air is mixed with 1 part of fuel. Thus on comparing if you make the mixture to 12:1 then 12 parts of air is mixed with 1 part of fuel thus air for mixture is reduced by 3 parts which leaves in rick mixture

Have noticed in many automobiles, the exhaust systems (silencer) is let out only on the right sides either in front or rear right. This some times creates nuisance, even i have faced this problem. especially while overtaking heavy vehicles. when these vehicles close their gas pedal all of a sudden it flushes out a huge black smoke which will hurt the drivers especially two wheel drivers who overtake. So why cant we have a change in this, cant we shift it to left ? Heard even there are some norms that we should let it out only in right side either front or rear. Why should it be so ?
