Automatic Carburetor For Corolla ee90

[talhatauqeer756]

Assamulaikum brothers, I am looking for a automatic choke carburetor for my corolla 1989 2e 12valve in Rawalpindi region.
The carb was cleaned and the jets were replaced but still its giving me 10km/l combined. Moreover, upon cold starts or even starting after a few hours requires it to be properly warmed up or else it wont have any power and stall immediately.
I am hoping automatic choke carb is going to solve this problem, if not so whats causing this poor fuel milage, please experts on this engine let me know.

Your car already has auto choke in carburetor. Aisin carburetor on Toyota 2E has auto choke from factory it comes in different specs though just need to make sure if its disconnected or removed entirely. If you are from rwp/isb then take your car to badar engineering sultan ka khu they can tune it and setup your auto choke.

Is your engine fully warming up under 5 minutes? Meaning…. Is the thermostat in place or has been removed?

Exactly,
that is the first thing to check,
I have seen people who have plugged the water pipes, and expect the carb to work properly ...

[talhatauqeer756]

No it needs atleast 10 minutes, otherwise it misfires and wont have any power

Idk my mechanic told me that 2e usually comes with auto choke maybe the previous owner might have swapped it so it'd consume less petrol.

Correct this problem first.

Thanks for bringing it up, over the weekend i will let my mechanic to take a look at it

in a carburettor engine, the carburettor is the very last item to adjust/tune, You have to make sure all and everything else is working correct.

engine temperature
valve clearances
no air leaks in intake
good PCV function
correct ignition primary and secondary parts
good compression.

etc etc.

only after everything is correct is the carburettor fiddled with - and tuning/fiddling is not just messing with the "idle mixture screw" - there are many more parts to a carburettor.

Turns out there is no sign of thermostat, it is missing, but as i just got the engine overhauled so the mechanic was saying that its an old car so installing a thermostat will be problematic, as the hoses and other cooling related pipes might be old, and as the summers are coming by so it can also cause the car to heat up.
FYI the temp gauge never worked since my ownership (its been on C), and the fan has always been direct

Fire your mechanic and hire someone not on drugs
