Flange-mounted magnetos are attached to the engine by a flange around the driven end of the rotating shaft of the magneto. [Figure 4-19] Elongated slots in the mounting flange permit adjustment through a limited range to aid in timing the magneto to the engine. Some magnetos mount by the flange and use clamps on each side to secure the magneto to the engine. This design also allows for timing adjustments. Base mounted magnetos are only used on very old or antique aircraft engines.
