I have taken my car to multiple mechanics who have no idea how to tune the carburetor, they say they need a diagram of what screws do what etc when to tuning the carb. Problem is that the carb in my haynes manual is different to the one I have, I think the carb I have is called a ''Mikuni Solex 32/36'' It is a stock carb. My car is A Mitsubishi Lancer/Mirage 1992 model cc coupe, engine 4G15 carb. pls help car is running very rich Thanks..
As far as i know, original stock carburetor for Lancer 1989-1992 engine 4G15 12 valve is Aisan Variable Venturi. It have 3 screws :
- air-fuel mixture screw
- main jet adjusting screw
- idle adjusting screw
and here's the document you may need :

There could be many problem if the carburetor type is solex 32 36....if your car is puffing black smoke all the time...means it is rich...okay..here in malaysia..this type of carburetor is useless hahaha....here is the solution...it maybe because your engine temperature sensor is bad...also check the thermostat for problem...and also your co2 sensor...because all of these is been controlled by ECU just like EFI system...also if cold starting is rough and black smoke comes out...it means your auto choke had a problem...hehehe thats all i can say...

Carburetors are for the most part simple its like flushing your toilet once it starts it becomes automatic the only problem is with idle or if you start messing with mixture and air adjustments.2 barrels are easily rebuilt on a small table with a 30 dollar kit and a couple cans of carb cleaner.Just follow the instrutions in the kit clear out all passages and replace the main ware parts and they will run like new and last for ever.Most vehicles after 1985 also have systems and sensors on them like TP throttle position sensor or idle compensator or pressure feed back system or oil comsumtion system but for the most part as long as the electrical connections are solid and the valve seats are clean and on air leaks with the exception of the TP this is a ware part and needs to be replaced from time to time every time you push on the gas pedal it moves
