Say Rcignition:
Could you explain a little more on the retard mechanism of the CH ignition? Since the engine is static timed at 28 degrees advance, I assume there must be some rpm below which the timing circuit allows full advance (for timing purposes). Also, there must be some rpm above which the circuit knows that you are flipping the prop and need the timing fully retarded. Is that how it works? Do you know what rpm the change occurs? If this is how it works, a very slow flip might bite you with a kickback because of full advance....true?
