## Probable cause

a total loss of engine power due to an excessively rich mixture setting in the carburetor.  The overly rich operation of the carburetor was due to the overhaul shop's failure to obtain the proper clearance between the float and chamber walls, which allowed the float to rub and hang up.  The overhaul shops failure to achieve the correct clearances was due in part to the inadequacy of the manufacturer's overhaul instructions concerning installation of the Advanced Polymer Floats.
