eh wait sorry they are supposed to be bolts instead of screw, refer this picture:


the 2 bolts securing the distributor to the engine block.
loosen them (no need remove) and move turn the distributor accordingly
towards front/front bumper/you while doing it = advancing
towards driver/firewall/rear = retarding

He tune with using timing light and one machine that need to attach something on the exhaust pipe and also with some screen showing heart beat like things when rev the car... is that CO reading?

Yeah I get it. I went through 3 different cams of increasingly higher duration on my 4 toto. The first cam was mid range torque 27x duration, upgrading to 28x one gave 4-5 whp across the upper band, finally settled on a 29x one, coupled with custom exhaust header finally worked well with the 4 toto's high end love, yielded 20 whp gain between 5000 to 7500 rpm.. Basically I came to conclude that 4 toto on our engine no point except for high revving, and that also must have large cams and well designed exhaust header to unlock its potential. But low end suffers.

And that was it, now back to 1 toto mode. Still using the 29x cam though. No more issue with low-mid range power.

Maybe the RON 97 sticker on Iswara fuel lid is because at that time there was no RON 95 only RON92 & 97? (RON 95 was introduced in 2009 to replace RON 92)

now that you mentioned it

just to confirm, it's the one circled in red and another one at the other side
i can see some gap there so i guess that must be it, but mine is damn tight, cannot loosen it

So, your 4G15 is not from the Fiore 4G15?

That is 1 good tuner! Were you using RON97 during the tuning? If yes, than it is optimized with RON97 liao.

My 1st Potong Night 8v ran very nicely with RON92 without ping at all Until too much pimple, put SKII half year come back, no choice to sell car when needed to drive with umbrella during rainny days

You need a swivel head socket type of spanner. If you use ordinary spanner, you are going to wear out the nut until it become rounded.

==edit==
BTW, how will you adjust the timing, using timing strobe light?

dunno wo

i use the spanner from the car boot, did not manage to adjust it yet
not such spanner at home,

where did you tune yours? and how much was it?

No, don't use the spanners in the boot for this job. Some of these tools are not suitable for heavy work. Especially do not trust the folding wheel brace (photo) for opening the wheel nuts - it will crack. Get a proper wheel brace.

You can buy suitable tough tools from DIY shops, hardware shops, hypermarkets etc

I tuned it in Kuantan, he charge RM20 for tuning... but seems like tuned to be more suitable for RON97

Mine also have that sticker, I willing to give RON97 a try is because of that sticker

I'm using RON95 that time... not sure how come end up like this
Got relate to autochoke? cause my autochoke seems like have issue, difficult to start engine when its cold... will die off easily for the first few seconds if I didn't give a bit rev to it

After all the posting exchange, it is quite confirmed that your butt feel gaves you better placebo, hence lighten your foot and at the same time the car gaves you better mileage

1) A magician that uses timing light, the firing timing has been optimized to the circumstances where the engine health stands
2) A magician that uses ping detector(the hospital heartbeat reader thingy) to read ping can further finalize your ignition timing settings. Usually when procedure 1 is completed, this is the next step to micro decreasing ignition timing to minimize/eliminate ping/knock. Usually they no longer use hand to push anymore(only will do counter clockwise at this point to further retard ignition timing), use a small thing may be test pen to lightly knock on the distributor to get the best setup out of it.
3) A magician that uses CO reader will know how much is the exact carbon monoxide released from your exhaust tail pipe, so he/she can adjust your air flow/idling throttle angle/fuel flow/FICD actuating angle(for aircond), headlights power draw adjustment(oh yes! our Swaga got this feature also!). Adjustment is solely justified base on how much CO emission when the magician go "bem bem" your car, but I bet most magician doesn't do the "bem bem" according to normal driving condition, such as 3krpm! Usually will bem until red line, which is unrealistic. If you go redline often, will you still be worrying on FC? Probably not. If you're an ordinary driver, what is your rev range? Probably 3krpm max
4) A good magician will repeat step no.1 and 2 all over again to reconfirm the 3rd setting does not affect the ignition timing. If ignition timing has to be reset, step 3 may need to redo depending on how far off step 1 is. Usually, an average magician already can gets step 1 right for the 1st time. Hence, there are really no need to repeat the process at all, but for the sake of confirmation, and yes that makes a difference between a good magician and a lousy magician. Usually its not about the skill anymore because the good 1 and bad 1 are almost similarly skillful, but the good 1 will go an extra mile to confirm his setup has been carried up correctly.

AND, for the price of RM20, even he didn't repeat you also should feel grateful ady Nowadays where to find RM20 tuning that involved all the above!

When was the tuning carried out? Carburetor got cuci or not before the tuning? This is a mechanical carburetor engine, any slight change of condition the setting also will deviate, depending on how bad the condition is. Unlike EFi engines can auto adjust everything according to engine health condition. Even our old 4G1x MPi that can't adjust ignition timing automatically also can adjust fuel injection rate to adapt.

Autochoke can be rosak without affecting much other than cold start idling speed. Definitely not affecting of what RON fuel you use

I really curious, how did you obtain the FC reading from your previous posts where you mentioned 14km/l? Is it the FUELLY way? Or the pay RM50, call it a tank? All my life, other than newer high compression vehicles, the 90's designed engine that has significant fuel economy between RON92 and RON97 was my CRX B16A The RON97 will really make hell lot of difference! Not to mention the power output, the fuel economy speaks for itself if it was the CRX. However though, the very same era my Potong Night 1.5S very much like to drink the RON92 red color devilish juice I feels like I can chase my own CRX with a ranjiao Plotong car when my mate is in my Hongda And, when I put RON97 cucumber juice in my Knight, tibai the bugger is like forcing my kids to eat vege lidat Go up hill will roll backward geh

where to find magician in subang/pj area? interested to try out once
