PA28 pilots reported experiencing carburetor icing at 10;000 feet. Their engine began to lose power; so they applied carb heat and descended to 6;000 feet. During the descent they regained full power and continued.

Narrative:
Filed for 8;000 ft but was getting bounced around. Asked for 10;000 ft and was cleared for climb to 10;000 ft. We were shimming through the tops with clear above. Reported level at 10;000 ft to washington center. Within a couple of minutes we began to lose power and started to lose altitude. At about a 200 ft loss; immediately asked ATC for lower; ATC responded by standby. Applied carb heat twice. At 9;600 ft washington advised 'he showed us at 9;600 ft and gave an altimeter setting.' asked again for lower and ATC gave us 9;000 ft. We complied and once again had a hard time staying at 9;000 ft. I asked for 6;000 ft and was cleared for 6;000 ft. During entire descent had carb heat on. We leveled off at 6;000 ft and all power was restored. We continued to destination with no further problems noted.mistakes made: should have had carb heat on longer and should have told ATC of problem; but was distracted by trying to hold altitude and figure out what was wrong. At first I thought it was a cable problem with throttle. Probably should have declared an emergency.
