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

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...

Something internal in the carburetor is wrong, maybe the accelerator pump seal or gasket is bad. Think you will have to put a rebuild kit in the carb. There's no outside adjustment for it being way too rich.
I really doubt the car is the problem, if it runs poorly at wide open throttle the carb is not the problem, check the fuel pressure 1st, it should be around 5-7 PSI, if that is ok then you may have a problem in the ignition system.
If this is a carburetor model,then the carburetor most likely needs work.Have you done a major tune up?Wires,plugs,cap,and rotor.Check all vacuum hoses,and replace all the old ones that look worn out and decade.If you do all this,and does not help,have the carb,rebuilt.Also change the air filter.
