My choice, Electronic ignition.
300rpm idle? never seen anything other than a hit-n-miss do that.
Someone has to be first to try it - I would if I wasn't $$$ strapped and had more than one engine.
I've personally seen a 750RPM idle... wouldn't even roll on pavement. Apparently it also gives more RPM with less fuel.
