How does that work? Must have to push the knob after pulling the cord. Is there time and the valve would have to be very close to hand.
Another idea is they only kick back because they fire backwards.
. They will not fire if the ignition is off. Try a pull with ignition off then switch on when turning properly.
Probably not a workable solution There would be a way of getting DC out of the primary coil windings. Have to be the older style magneto with the separate module.and would need some clever electronics to operate an electrical valve.
Another idea that will not work.
Persevere with the decompressor valve I think Norm.
