Do you have any idea how many years I've been telling people that's the way they should run? Worse, any idea how many people have told me they just love their ?? engine even though it burbals to high heaven? There's no reason to have an engine that does that. Right Joe? There's a lot of good engines out there. There's also lot of "good" engines that could be done a little better.
