lemme ans ur Qn one by one.
1)wat do the mechanics do when u tell them to tune the
engine?
engine cannot tune wan lah. only can bore.
i tink u meant tune the carbs rite...
each carb got 2 screw, namely the pilot screw and the other wan
forgot the name liao. one is for the idling and the other is the
amount of air intake.
the carbs control the amount of fuel and air mixture to burn
with.
the correct mixture would mean performance lor.
poor mixture would result in wither too rich (petrol more than air)
or too lean (air more than petrol)
too lean ithink will have no power ah. where as to rich will lead
to carbon deposits on the piston head leading to a piston jam in
the long run. how long i dunno liao.
2,3) i think Qns answered liao
4)heard after proper tuning dun eat 2t so much, true anot?
no. tuning dun affect 2T. the 2T pump does.
open big nvm, too big no enuff lubrication of the piston will jam
wan.
an example would be .... hehehe ...
u knoe i knoe lah
