Hi all,

I was doing some carb diy cleaning and decided to try and tune my AF ratio, want it to be leaner as I think it's running rich (got those smelly exhaust, plus FC is not so good) so few questions, been trying to look in internet but can't find much helpful info:

1. The red circle is the AF screw, correct?
2. With AC off idle screw turned out until it doesn't touch the linkage, I tried to tune the AF ratio
3. When the screw is completely removed, the engine still runs -> is this running at fully rich?
4. When I screw in this AF screw, at one point the engine starts to hesitate and want to die off (is this getting too lean, i.e. not enough fuel?)
5. I backed out a bit and then engine RPM seems to be ok around 900 (AC off idle screw still not touching)

Few things I noticed, after a while when I start the engine, the RPM is low (maybe 600) and almost wanted to die off. Does this mean too lean and I need to screw it out?
Without any other changes, meaning as low rpm scenario above, after some driving, the idle RPM shoots up to 1300 or so... Is this normal?

Just trying to do some diy trial and error tuning

Also, does anyone know if I can remove that 'protective cap'? so difficult to turn it (I don't have old spark plug lying around) so had to use a pair of pliers - that's where you see all those 'teeth' marks there...

Any suggestions/advice from gurus here most appreciated, thanks.

hi guys, any tips on how to improve fuel economy for 1997 iswara 4G13  ?

my car fuel efficiency is only about 10km/l which is very very very bad and it has not much power

also during idle, exhaust got petrol smell.
advanced the distributor now low end toque is better but no impact on fuel economy.

any tips to improve fuel economy ?
make the fuel air ratio more lean ?

thanks in advance

you got from kweng also right? went back to him for the s-flow or went else where?

im thinking of getting it done before hand, so at least got a week+ to test drive/tune as needed before track day and i can use it on the track straight away.
rm20, ok la, can pay postage 

and whats that MVV stuff?

hard to dyno a/F ratio rofl.

not to mention, main reason to tune usually are FC issue, how to dyno that? 

You tarak trouble with pak polisi so far? So getting a projector is a must 
How much did it cost you?

MVV = Mitsubishi vertical vortex bro lowyat82 so u decide edi to race or not to race ? ur car also stock-nia de leh xD

so who's the best? sid or unker fred? what difference? quite confusing for option here @@

i see... dyno tune is only rm70 ? i heard my friend say super expensive...
and yes, the af has been tuned before...

Dyno tune is not Rm 70 juz to put ur car on dyno itself so far i found cheapest is at RS Dynotune Puchong Rm 70 for tuning have to add another few ten bucks... forgot how much... not more than 50 for sure...

where can i find ramly? just now you guys mention Dynotune, izzit full moto tuning with dyno accuracy? how much to do so and where?

tq
