As far as strategy, this saw is to be my go to saw. Squish ended up around 20 thousands. Timing from tdc is exh 104, transfers 124, and intake of 76. The ports widths are 60 percent of the bore.
I ran the saw with the factory zama el18. I was three turns out on the high side. Tried a walbro 159a. Ordered a walbro 191 and it tunes out better.
I am on about tank #4 and so far so good. Current chain set up is a 18" .325 Oregon chain. Real happy with it. It will cut for over 1 hr and still have fuel in the tank. Last time I ran it, I was getting tired thinking it had to be close to being out of fuel. Well, jonsered 1/ joey 0. The saw cut more wood than my body could take for 1 tank.
