Within the last year have gotten into racing small engines and I love it. There is one thing that I don't understand. The WF engine seems to be briggs top of the line engine but it comes with a 7100 rpm limiting coil. The animal has a 12k coil, why not the other way around? The WF has also a billet rod and the animal the squeeze cast one but again it is "allowed" to rev higher. Last but not least, the header. The WF has a small dia exhaust compared to what most use on the animal. Is the header another limiting factor or does it help with low end power? Please explain, thanks
