Dear Friends,

I recently bought one second hand unit, LMST model year 2005 from a car dealer. Condition is good, but the big problem is the terrible FC! For a full tank of RM70 (RON95 at RM1.80/litre current price) I get only about 350km with very very gentle driving mostly in town with little or no traffic jams. I believe this model should give around 450km per tankful based on the kind of driving my son (it's for him to drive to college etc).

I have tried everything I know, like replacing the stupid rear exhaust, changing the rims/tyres to 13" 165", and finally getting the carburettor serviced although I am not if the young mechanic did anything serious work on the carb. I have in mind to get rid of this thing although I will suffer a loss of a few thousand, but my son thinks that we should get a good mechanic to fix it up properly, as he prefers to drive a 'normal sized' car as opposed to a Kancil or a Viva etc.

Can anyone here please help me recommend a competent mechanic? Any suggestions please? Btw, I am in PJ area.

Thank you.

i think u have to retune your carb. Not easy to find an experience tuner for carb. Even proton one they count on modern device.

Agreed , guess you gonna retune then afterall . Your f/c are really bad . by the way , have you check your fuel filter coz a clogged/dirty one will also cause high f/c ,too .
PATIENCE !!! PATIENCE !!! PATIENCE !!! IT'LL GET YOU THE BEST WHEN TIME IS RIGHT AND SO WILL BE THE PRICE

Many reasons affecting the FC. Engine component not maintain well from previous owner also one of the reason.

Thanks for your advice, friends. Looks like I have to find me a good mechanic to tune up my carb - any recommendations for a good mechanic? I have also changed the stupid noisy useless rear muffler to the standard Iswara one which is much quieter.
