Over the last 7 months I have been pondering hand starting a lightspeed system if the need arises.
I understand the system is advertised to not fire untill TDC when hand starting but looking at the setup makes me question a mishap.
If I understand it correctly the crank pickup sensor does not care which direction the crank is rotating? maybe I am wrong and if I am this is where my problem is. If I am correct the following is the problem I see waiting.
If I start the stroke of hand starting the engine and pull the prop through far enough to make the magnets at 42 deg advance pass the senser this will activate the ignition so that the next set of magnets at 0 deg will trigger the fire.
What happens if you go past the first set at 42 deg then run out of steam (pull) to complete the stroke (never take it all the way to TDC) and let the prop come back to the 42 deg magnets again? I would assume that it will fire on the way back.
Thoughts?
