Stator driven tach is usually 12 pole some early V6 were 10 pole.
most tachs are made for 4 stroke motors
which spark every 2nd revolution
so in turn a 2 stroke sparks every stroke
so most of the time
setting a tack for 2 stroke,,,,,,,, double the pulse
the 3 cyl motor the tach will be set at 6 pulses,,,,,,,,,,,,,
there is a few odd motor pulses,,,but the majoraty falls in the double the cyl catagory
