Analysis

The acft nosed over during a forced landing after a power loss. The acft collided with tall corn during the landing rolland swerved into the corn. Examination of the carburetor revealed pieces of a soft brownish-white somewhat elastic substance in the float chamber. It was very similar in nature to a teflon sealing tape which was used on the threads of the fuel inlet fitting screwed into the inlet part of the float chamber. A piece of tape was loose & folded over the bore of the fitting. The builder stated that he used the tape when installing the fuel supply line to assure no leaks at the carburetor.
