When it starts its putting out too much white smoke, runs abit lumpy, running too rich, cleaned carb out a few times seems fine, what else could it be? i have put a second hand carb on it 2 months ago, and it was running fine before, so i think it may need a new carb, but just want to make sure its not anything else? thanks

You didn't say whether it is gasoline or diesel, So I will guess it is a gasoline engine. It sounds as though the fuel injections system is leaking fuel into the manifold or combustion chambers while the car sit idle for a while. This would cause the black smoke on start up. After it burns off the extra fuel the smoke would clear up and the enginewould run smoothly. The only way to find out if the injectorsare leaking is to take it to a mechanic. If the car runs ok, it would not hurt to drive it like it is until such time you could have it repaired.
replace lambda probe expensive but it will run ok after that, i dont know if you know how they work so here's a brief: lambda tells ecu how rich the exhaust gasses are, ecu ajusts fuel input as neccasery eg lambda says not anough fuel ecu puts more in and the other way round.
so if your lambda is covered in **** when you get it out just clean and put it back, if it looks clean enough it needs replacing!! jezza
White smoke indicates that it is burning oil. The smoke would be black if it was running rich. So probably the rings will need to be replaced eventually. These mowers are prone to problems but the carbie is least likely to be the problem. So before you adjust the carbie take the cover off the top and give it a good clean and check that all the hoses are connected and are not cracked. Then make sure the airfilter is clean, blow it out with an air compessor or better still get a new one. Then try it out agian. If this doesn't help there is two screws on the carby marked L and H. Turn these only 1/8th of a turn at a time and note or make their current position. Start with the H scew with the mower at full revs. Turn anti clockwise untill you get max revs then turn it back a bit. Running too lean will over heat the motor and damage it. Then if needed adjust the L (or Low)screw. If you get black or grey smoke when you push the throttle up from idle to full its too rich so turn clockwise. If if slows before it picks up to full revs turn anti clockwise.
was the code for rich or lean? may try cleaning mass air flow sensor. it is in the air intake tube and has a flat wire connector. take out of tube and take four torx bolts out and clean with mass air flow cleaner or brake cleaner and put back in when dry. or it could be a bad wire on the o2 harness. look for chaffing or broken wires in harness by o2. also could be the exhaust system has a slight blockage. could also be some other things but try these first.
Have you had the injector recall check carried out? There is a problem with these injectors and this produces the symptoms you are describing. I suggest that you contact Isuzu direct for help. They have been very helpful in the case of my trooper
