I would like to get comments on whether magneto or electronic ignition gives the best result.
I have tried both and have found the electronic is better for idle but they are not made well and I have 6 or more failed units and the time involved in finding the fault, be it hall sensor, ignition module, broken connection etc is troublesome. I have yet to have a magneto fail and think the extra rotating mass helps with power output and vibration. I have also found I get more rpm using a heavy prop like a master rather than a wood prop, and conclude the extra mass of the fly wheel helps to carry the motor through the compression stroke.
