What a place to drop a big ass tree! Slip up there and the new house is badly damaged.
On the Husqvarna........I know this guy.......
As far as compression goes........when you couple slick port work, and a few other little tricks with big compression you end up with an engine that is extreme in the amount of torque it makes......that my friends is a fact.
Is this a great idea on a saw that will be used every day in a work setting......probably not.
David was more interested in a saw that he could take to a GTG and run a 9 or 10 pin on........but he also wanted to be able to strap on a 32" bar and a 7 or 8 pin and buck up a big log. This is what we came up with.
On most of the dedicated work saws I build the compression tops out at 200psi or less.
Though for all out performance I'm a firm believer in compression as a torque multiplier. I learned that a long time ago while building SBC engines for drag racing.....
