 Inspect the float valve and valve seat for
 damage or clogging.
 Inspect the float valve and valve seat
 contact area for stepped wear or
 contamination.
 Worn or contaminated float valve and
   valve seat must be replaced because it
   will result in float level too high due to
   incomplete airtightness.

     turns until it seats lightly and then
     make a note of this.
   · Do not force the pilot screw against its
     seat to avoid seat damage.
