That's exactly right. But in the case of a weedeater, blower and some other engine conversions, sometimes a sensor attached to a hose clamp is used, or a round tubular sensor is used. In those cases, the sensor cannot be flipped over, and you MUST install the magnet correctly. I usually power the system up and see which side of the magnet triggers the sensor. Then I color that pole of the magnet red to be sure that I install it in the prop hub the right way.
