Yeah. I have the mech do everything at one go. Clutch set, clutch cable, clutch switch and seal, bearing, flywheel oil seal, lower arm and the drive shaft plus the absorber link and also steering boot coz the mech say since going to do the drive shaft, do together since it going to involve the Gearbox. I was quite surprised it was still the ori clutch seal was original from day one though I had them replaced at 200+k. Some mech are seriously asshole....

I remember you posted a diagram of the autochoke's channels.

Can you post it again ?

I was looking at the choke's appearance as shown in the photo.

It looks like just a bolt-on with three screws to the side of the carburettor.
I think it just revs up the idle speed with the movement of the cam at the
end. I don't think it enriches the mixture.

Wow, I didn't know this Hup Seong in Segambut seems to sell
everything, even cylinder heads and camshafts.

You can even get the thermostatic valve here.

Mostly China and Taiwan parts though.

Jammed choke nearly caused an accident
in this guy's case.

Similar to those cruise controls devices jamming at speed.

1) The autochoke piston (aka enrichment rod) not only
alters the throttle idle position, it operates some air bleed
passage to change the air-fuel ratio (AFR).

2) Different engine loads and temperatures require
different AFRs.

3) The vacuum line that goes to the autochoke operates
some kind of device(s) that also alters the AFR.

Thanks for the site. For the thermostatic valve, so far I found only 2 with price like what you mentioned earlier:

how to know if thermostatic valve is spoil ?

Talking about accident, bad day yesterday.

As I was about to drive out from Hartamas yesterday, moving
along slowly in a jam at the traffic lights, this guy in a Nissan
X-Trail bumped into my rear.

Quite a strong, loud bump. I thought my rear really gone in.

Came out, the guy said he "dropped his food".

Surprisingly, our Iswara's rear bumper is quite strong. Two women
near my house (one a Malay girl right outside) already bumped there
with no serious effects, other than a small broken lower corner of
the number plate there, and minor scratches.

This time, the left edge, where the "L" wraps around the right signal
light and the right side of the boot, came out a little at the top, where
the rubber strip runs.

The right corner of his front bumper (X-Trail !) had come down a little.

The guy said he was jobless, buying food for his kid, etc etc and
showed me his wallet with what looked like just two $10 notes
there (driving a metallic gold X-Trail ?).

I gave up on the guy. I told him that the two women who had bumped
me there earlier didn't even cook up such stories and compensated me
on the spot - the Malay girl had given me $100 without even me asking
(and I found out later she was actually jobless), and this guy was a
married man, probably late 30s !

Finally he took out another $50 note from wallet and gave it to me
along with the two $10 ones. No choice but to accept it.

I told him if it had been a pedestrian (like a schoolkid crossing the road),
he would probably be going to court now for dangerous driving, like the
young girl who went in the wrong direction last two weeks.

Took it to the usual mud guard man in Sungei way, who was busy with like
five cars in his workshop. He took out his super glue (those $1 China
plastic bottles) , dripped along that part of the rubber strip, and taped
up it crudely with those paper masking tapes, telling me to remove
them later.

I asked him, what about hammering the metal bracket underneath back
to shape ? He said not necessary, won't make any difference since
that was the side, etc etc.

Took it home, then noticed that part of the boot along the side bumper
had also dented in a little, but very minor.

I took some photos, used my sister's phone to Whatapp them to another
former mud guard man from Cheras, now a used car salesman, who
told me to just leave it alone.

i face this before. based on my experience it is not jammed choke because the choke never can rev your car to 3.5k rpm, max is about 2.5k rpm only. its the throttle body shaft jam. its usually wont happen if u drive economy way ( less hard accelerating ), but it happen once after u release your feet from fully throttle or hard accelerating.

i did not send to my mechanics. i just have some lubricate spray to my throttle body shaft both side left and right. everything is just fine until now.

another way, just open your front bonnet and push the throttle body to idle position. it wont be hard to push just little only.

i think my saga lmst year 2007, the choke have been factory modify. there is only one vacuum hose connect to choke and 2 water hose ( in and out ) only. the thermostatic valve vacuum hose i still have some hard time to track it.

Oh, you mean your is fuel injection ? The throttle body has a
tendency to jam ?


That also happened to me at least twice in my old Toyota, with the
twin venturi Aisan carburettor.

First with the old carb, then again with the new carb which had replaced it,
after only just over a year.

The second time, this "smart" mechanic below my office was teaching
me how to "start this type of car in the right way". With the engine off,
he stepped on the throttle pedal all the way down, then turned the key.

Immediately the engine revved up to what sounded like 5,000 rpm !
I thought my timing chain and valves were going to fly off. The idiot
didn't seem to know what had happened.

My exhaust was blasting out lots of black smoke, and the customers
in the eateries just across the road were covering their faces!

Opened the bonnet, he kept looking at the carburettor, trying to figure
out what was wrong. Luckily, he managed to free the linkage after about
30 seconds, or my timing chain would have flown out.

The butterfly throttle flap linkage of the secondary venturi is hardly
ever used and will jam up over time. I had written a letter to Aisan in
Japan then, screwing them up for a poor product.

One guy told me it also happened in his old Toyota KE30, the engine
revving up to 6,000 rpm, and his timing chain broke.

Luckily these old Toyota K-series OHV engines are non-interference
types, so his valves and pistons were not damaged.

If this happens in our "modern" Mitusbishi OHC engines with the
useless timing belts, be prepared for a big repair bill.

Yes, the one in the Iswara has only the center vacuum pipe too.

My saga lmst year 2007, After i repair the auto choke, the fuel economy increase significantly and power is come back again, nice idle sound. Wont shake like hell in idle and morning as well. Morning start the exhaust have some water vapor . After repair choke, new set of spark plug, flush and change new type of engine coolant ( oily type of coolant) and re-tune now i get about 480km per 40L. very nice.

The tuning shop help me adjust the co level to about 2% only ( on hot engine, after a ride ), is that correct ?

yes throttle body shaft is possible to jam. I think is because of dirt around them. Last time mine is continue rev to 5k rpm after 2nd gear full throttle for potong kerata at hill road. in 3rd gear i found uncontrollable, i stop at side and open full power of my air con to lower the rpm. I know is throttle body jam, a huge gap between the choke and throttle body position.

do u know where the center vacuum pipe connect to ?

Inside the autochoke there are breaker and power jets.

Where's the tuning shop and how much? I plan to tune oso if nearby my area, thx

i stay at kuching area, are u the same area as well ?

opps, i'm in penisular, subang jaya area

You mean the two jets and valves are inside the autochoke ?

The whole choke cannot be simply removed and the carburettor
left as it is ?

I remember one taxi driver disconnected the two water hoses, and
simply jumped the two pipes on the intake manifold with one of these
hoses.

He had a dual fuel system - LPG or petrol.

That "Ancient" guy seems to have disappeared.
