Unfortunately the most important picture got deleted from my camera, Not happy.
If I need to take it apart I can retake the pic.
Saw started life as a little 60cc saw. So of coarse not good enough for me. I took a 68cc cylinder
and had it bored 3mm over. With the help of some great friends who have more access to pistons
we found a close match. Cylinder went from 49mm bore to 52mm. So ended up using a piston
from a cut off saw. Had to have some machine work done. About 60 thou removed from skirt
and 20 thou from crown but leaving an off set pop up do to the combustion chamber.
Compression is before initial start up so it is a tad high do to assembly oil. Carb is off a larger
saw but fit perfectly and is about 80 thou larger bore. Muffler is from same friend but I gave it
the extra port on the recoil side. Saw is running and is very snappy, And sounds awesome. Hope
to get time today to give this new 76.5cc saw a run.
