The carb has a small finger strainer on the inlet nut. Pull the fitting to the carb then pull out this strainer (loosen the inlet nut on the carb - the strainer is soldered to this nut). This should catch most of the debris, but a safer bet is to pull the carb, separate the halves and clean out the needle/seat, main jet and metering passageways. It shouldn't take but a half hour once off. You'll need the main carb gasket for reassembly. It's likely that blockage upstream of the carb caused the engine issues, but you don't know. You could also test fly and then clean the carb if you still have issues, but you run the risk of engine sputtering on the test flight if the blockage was in the carb.
