Analysis

After arrival, the plt decided to make a low apch over the arpt to check the rwy. As he initiated a go-around at about 100 to 200 ft AGL, the eng ran rough & would not develop sufficient power to sustain flt. An emergency landing was made on a 'logged-out area.' During the landing, the acft hit small trees & stumps, & was damaged. An investigationrevealed that the wrong type of carburetor was installed on the eng & that the carburetor float would 'hang up' intermittently.
