shifting shuts my car off

that black plastic canister on the right front corner of the engine compartment,it is filled with carbon(evaporative emissions canister)when they go bad............the carbon(lil' black round thingies)end up in the carburetor and cause a lean condition,the carb looks like it needs to be rebuilt anyway but if you find those lil' black thingies in there something will have to be done with that canister also(trashcan comes to mind) but you may have to replace it depending on the laws of you state.does it stall after warming up if you turn sharp?if so lil' black thingies are probably at fault good luck.
