Greetings...
First of all, i m driving a Small little kancil 660cc standard.. I met several problems and wish to consult and ask for idea + recommendation from dear sifus...
1. Since my contact brush have prob, instead of changing the brush over and over again, i decided to change to CDI 850cc distributor for my 660cc slk... It comes up with a little "choking" problem.. When i shifted 1st gear, release the clutch slowly, and press a little bit of gas pedal, my car is not accelerating smoothly.. It kinda like an EFI car with fuel pump prob.. Chok Chock a bit...(for 1 or two seconds?) But if u shift 1st gear, release the clutch while press some amount of gas pedal, it only chok for 0.5 sec? or no chok at all... Only for 1st gear and second gear usually this problem...
So i went to change fuel filter, brand new set of aerospeed plug cable with iridium plugs.. It becomes better but few days later still the same...
Especially when open aircond, sometimes, it chok and will mati engine completely while i press a little bit only for gas pedal....
Then i went to few workshops around, only one workshop met this problem before. The guy said several years before, one 660cc stock kancil came thr with the same problem too, with CDI 850cc distributor.. he checked everything, cant find out the reason and finally changed back to 660cc contact, the problem is gone... lol
so i changed back the 660cc contact, now is pretty fine, no more problem... :mother of gosh:
My question is wat is the problem here yeah? is it 660cc standard kancil cant use CDI 850cc distributor? lol I seriously prefer the 850cc distributor... ( i believed many of them changed from 660 contact to 850cc distributor )
2. My old radiator is old dy. so i bought a aftermarket radiator, HKS on top of that... lol.. well, don bother that... I changed L2 hose too. then i am recommended to equip a aftermarket forged racing fan (i think it's the 12") for the new radiator.. so i juz go for a try... A new radiator with forged racing cooling fan cuztomised on it. Well... While idling, switching on the aircond, the temp gauge shows tat the temperature is around 8x... Will still go up though... until 88 degree sometimes.. While switching the F.Racing fan to my standard stock fan, the temperature barely go up 80C while idling... Usually is 78? the most is 80C while idling for one hour...? The time taken for forged racing fan to cool the water from 92C (when fan engage with aircond off) to around 70C is longer than the standard fan use... and the aftermarket fan cant get my temperature to be lower than 70C to the point where the fan stop engaging (around 58C) while the stock fan can get me to 58C....
My point is the aftermarket F.R cooling fan seems to be weaker than my standard stock fan? Is it true tat those forged racing aftermarket fan only can be used for additional aircond condenser fan? nt efficient enough to cool the radiator huh? So suggestions? switch back to stock fan? 
Currently using the forged racing aftermarket fan though....
3. Last time, i faced a problem with my fanswtich which don engage, so my temperature went a bit high.. I went to workshop, and get myself a L2 racing fan switch, claimed to engage at around 71C... Well, it works... (my thermostat was removed) The fan engage while the temperature is around 72 degree? But for two three days later, the fan stop engaging at 71C... so i switch on the aircond, to let the fan running all the time until i went to the workshop to check wat happened... they said the fanswitch kong dy.. i went to claim warranty, and changed another one... still the same... the fan don wan to engage even the temperature already reached 9x...

so i ended up with buying a donno wat brand fan switch from the workshop.. it engage kinda late, around 92C... but fan only switch off at very low temperature, it's around 58C...
My question is..
Can standard kancil get a L2 fan switch function normally? Is the current fanswitch normal? i mean engage at around 92C.. cause i thought stock fan switch engage around 85C... (btw, temp took according to temp gauge) (according to my standard temperature meter, the fan engage only when it's at half... last time, i remembered the temp never go more than 2/3....

)
4. I changed my clutch kit few months ago, but 850CC one... The workshop claimed tat 660cc with 850CC clutch kit is better...like more contact... sometimes, when my fren or family drive my car, they get to shift but,got "kraaaakkk" sound lol.. i was wondering if the bigger size 850cc clutch is compatible with my 660cc ? Any idea?

Need to change back 660cc clutch kit?
Thank you all for your time, your advice is much appreciated... thanks again...
