The car runs, but floods badly. When it idling, the left carb seems to flood itself no matter what i replace or adjust. When you rev it after idling it almost dies. Also when it warms up, the revs hunt around while idling. The carbs are Stromberg 175 cd2.

what type vechicle many things cause rich fuel mixture check code if you see check engine light flashing could have bad sensor like map sensor faulty egr valve faulty mass air flow sensor.faulty oxygen sensor.weak ignition coil.bad fuel pressure regulator.if you have carburetor engine could have stuck closed choke valve or float in carb gas soak sticking causing engine flood.
what vechicle type model and the year.older cars carb type if automatic choke not working or vacuum pull off not working carb will flood out engine.for cold start up engine need good spark and fuel.if engine flooding could have weak spark due to worn out spark plugs and wires.could have vacuum leak or bad engine coolant temperature sensor.dirty air filter.dirty fuel injectors.
Well first off what year and kind of Jag is it?That will make a difference on what might be the problem.If it is a carbureted model, it sounds like you either have a simple fuel line leak going to the carb so when your car sits fuel drips out and gives you the gas smell and then sucks air when you rev it up.If there is no line leak,sounds like your float in the carb is sticking open and simply flooding the carbs with gas,hence the smell and the bogging out at rpm.You would need a carb rebuild kit with float to fix that problem.That way you have gaskets and floats to fix your carb.
It sounds like the carb. float is set to high and /or the needle and seat has some dirt in it allowing to much fuel inside the carb.. This will allow to much fuel into the engine.It seems the carb could use a rebuild and dont forget to replace your fuel filter.I hope this helps.
