Based on fuel consumption alone what saw will be more efficient? And by how much, will one blow the other one out of the water or will the difference be minimal?
.....
Also the 4 port designs of the husky vs the older stihl model have potential for cleaner scavenging and less intermixing of new charge and exhaust. Why do you think newer stihls under strict EPA rules are going to 4 port designs? The 4 port design should also be another efficiency point for husky, from a practicle stand point it allows lower transfer port timing to achieve the same RPM allowing more exhaust to escape before transfers open reducing intermixing and reducing the amount of new charge going out with the exhaust and wasting fuel.
