" Ignition advance curve "


Hello everyone,

I must know about advanced curves, or timing curves, I don┤t know its technnical name. I think it would be difficult to find info about them, about curve for each manufacturer and model, could someone help me

┴ friend of another forum has given me a curve, the attached one, do you think it will be good for all of our gasoline engines

Thanks

Good flights

Hand propping an engine is the equivalent of about 400 rpm, our model engine ignition, at least C&H Ignitions sense this and retard the timing to 6 degrees BTDC. The curve is very short on our engines being all in, (28-32 degrees) by about 2,500. Early on CH's Synchro Spark was a separate unit, I have at least one that has 1,500 written on it.
