When the magnet aligns with the coil, you get 1 positive pulse, although it took 2 magnetic poles to do it, those engines produced 9 pulses per rotation of the flywheel, I just wish the internal potentiometer give you enough range to compensate for the missing pulse.
It was not the case with my 1650 tachometer but I already knew that and after I take a good look at the diagram I substitute one resistor
for a 10 turn 1/4W potentiometer, now it's accurate but who really need a RPM on a garden tractor? For what purpose? For me it's was just a fun totally useless project but it may look cool on my walk behind snow blower.
A simple rule...Keep the gauges and diagnostic tools on the bench or in the toolbox. For mowing and snow blowing a good beer holder is all you need
