I don't want to disagree with anyone about this, I understand how a battery powered ignition can give good spark just above zero rpm thus easier starting. I have also readed about mechanical throttle coupled advance sytems & electronic advance system that if i understand it correctly would also give a better idle & better transition. Would this walbro ing. module with the advance (actually retard) curve built into their cdi magneto ingnition modules & do the same. The info from the web site shows different modules with different advance curves and out puts what I looking for is what is the module part number for the different curves. All info would be greatly appreciated.

Thanks Hubert
