The Aircraft Timing Indicator Model E25 is a unique device that locates the relative relationships between the crankshaft, magneto point openings, camshaft and valve timing.

Easily attached to the propeller spinner with mounting bands that are included with the unit, the E25 quickly and accurately (within ½ degree!) locates top dead center. The result: the all-aluminum Model E25 speeds up and improves the process of timing magnetos to the engine. 

With its easy-to-read dial and 18mm, hardened aluminum piston stop, the E25 is a snap to use.

Note: Piston Stop is included.
