Question for you soarrich...

I checked the timing on the engine. The plug fires twice on my engine. Once when the magnet first reaches the sensor and then another time when it leaves the sensor. The second time (as the magnet leaves the sensor) appears to be exactly where it needs to be (30* from TDC). Is the first spark OK where it is, or should i adjust the sensor so that the first spark is at 30* from TDC?
