Chapter and section verified against FAA-H-8083-32B, 2023 edition, on 28 August 2026. Page numbers are deliberately not cited: they move between printings, and a citation that rots silently is worse than a coarser one that stays true. Checked by our handbook citation check against our index of the handbook's chapters and sections.

A control that reaches its stop in the cockpit before the carburetor reaches its own is the classic rigging fault

The operative sources

  • The engine manufacturer's adjustment procedure and target figures for S7, S10 and S23. These are theirs, not the handbook's, and they are specific to the engine and the installation.
  • The aircraft and engine manuals for fuel pressures, filter intervals and nozzle data.
