TUN 'R graduated setting rod for ignition adjustment (Ø14mm thread)

Here is a standard setting rod, at a very low price it will allow you to adjust the ignitions with ease, it is certainly less practical than a BUZZETTI or TUN 'R luxury, but it is also less expensive! For use it is relatively simple, position the piston at TDC, just touch / brush the piston against the rod of the rod, and put the line of the nozzle face to zero, tighten the lock nut against the nozzle so that it does not move any more, your rod is therefore at zero and your engine at PHM (top dead center).

It only remains for you to screw, if your engine controls for example, make a full turn by screwing until you put the line face down to zero you are therefore at 1mm before TDC, then tighten again until number 2, you are therefore 1.2mm before top dead center.
