IGNITION TIMING KEY
This simple tool makes it possible to accurately
adjust the advance, excluding all inaccurate
readings, which is a problem that even the most
expert instructors run into.
To use the key, it is sufficient to insert the
projections - found on the lower face - into the
flywheel fixing holes in the rotor of the new
inner rotor ignitions. These holes are free because during the advance regulation phase, the flywheel hasn’t yet been installed.
Once the rotor and key have been joined, the flywheel can be moved by rotating the tool until the regulation hole is aligned with
the right-hand fixing hole of the stator. To make the alignment, insert a pin or drill bit with 5 mm diameter.
With the rotor and stator perfectly aligned, to set the advance with
absolute certainty all you need to do is shift the stator, rotating
it thanks to the regulation guides, making the measured piston
position coincide with the comparator.
