Narrative:
En route I experienced engine roughness. The WX was bad and my destination airport was about to close due to approach lights inoperative. When my engine stared to cough I declared an emergency and landed at my nearest suitable. I never at any moment lost full power. After I safely landed at ZZZ I analyzed the flight and realized that I was in a carbureted airplane (my normal is a fuel injection); and failed to try the carburetor. It did not cross my mind that carburetor ice would be a factor in a cruise power setting. No incident or damage was filed.

Narrative: ENRTE I EXPERIENCED ENG ROUGHNESS. THE WX WAS BAD AND MY DEST ARPT WAS ABOUT TO CLOSE DUE TO APCH LIGHTS INOP. WHEN MY ENG STARED TO COUGH I DECLARED AN EMER AND LANDED AT MY NEAREST SUITABLE. I NEVER AT ANY MOMENT LOST FULL PWR. AFTER I SAFELY LANDED AT ZZZ I ANALYZED THE FLT AND REALIZED THAT I WAS IN A CARBURETED AIRPLANE (MY NORMAL IS A FUEL INJECTION); AND FAILED TO TRY THE CARBURETOR. IT DID NOT CROSS MY MIND THAT CARB ICE WOULD BE A FACTOR IN A CRUISE PWR SETTING. NO INCIDENT OR DAMAGE WAS FILED.
