## Discrepancy

BRASS FLOATS, PN AV30-768 WITH PN 29-182 TYPE NEEDLE RETRACTION CLIPS HAVE BEEN FOUND WITH SEVERE WEAR IN THE FLOAT FRAME CAUSED BY THE END OF THE 29-182 TYPE CLIP WORKING AGAINST THE BRASS FLOAT FRAME.  THESE FLOATS AND CLIPS WERE FOUND IN HA-6 CARBURETORS ORIGINALLY MADE.  THE 29-182 TYPE CLIP IS INTENDED FOR USE WITH FLOAT FRAMES MADE OF STAINLESS STEELE.  THE BRASS FLOATS EQUIPPED WITH THE 29-182 TYPE CLIPS APPEAR TO HAVE HAD THE BRACKET, PN 178-48, REMOVED TO WHICH THE PROPER WIRE FORM NEEDLE RETRACTION CLIP PN 29-194 ATTAHCES.  EXCESSIVE WEAR OF THE FLOAT FRAME COULD RESULT IN THE FLOAT SYS STICKING AND COULD RESULT IN FUEL FLOW TO THE ENGINE BEING INTERRUPTED OR RESTRICTED.  PN 29-182 FLOAT CLIPS ARE NOT APPROVED BY THE CARBURETOR MFG FOR USE WITH BRASS FLOAT FRAMES.  SUBMITTER RECOMMENDS THAT CLIP TYPE 29-182 NEVER BE USED WITH BRASS TYPE FLOATS.
