Yup. I'm gonna drop the cylinder a bit more and give it a bit more FW advance. Hopefully I won't need to touch the ports
What were stock timing #'s? I have a red and black one converted to 272. AM jug tho. Curious about the stock oem numbers

Stock numbers were 71/121/104. The saw is built with AM cases. It was a head slapper without a base gasket. Stock squish with a .020 base gasket was .013"
