Micrometer for Ignition Timing Adjustment (M14 × 1.25 mm)

A precision micrometer designed for setting ignition timing. Simple and effective: one full turn equals exactly 1 mm adjustment.

Why it’s needed

The ignition timing determines when the spark ignites in relation to the piston’s position. Using a micrometer, you can accurately locate the top dead center (TDC) of the piston and set the ignition accordingly. Many performance ignitions require this level of precision to work properly.

⚠️ Note: Incorrect ignition timing can cause power loss or, in the worst case, complete engine failure.

How to use

Insert the micrometer in place of the spark plug and rotate the piston – the scale will show the piston’s position with millimeter accuracy. For a step-by-step guide, check out our internal rotor ignition timing tutorial.
