Well my 660 broke the crank and has to come apart anyway/already is. I figure I will make an attempt to get a little more out of it. This saw still needs to be able to serve a purpose as a firewood saw. I put the new crank in and my timing numbers are Intake - 166* Exhaust 174* and transfer - 114*. It also has 190 wet compression, not sure dry.
