660 compression?

[Ray Bennett]

Im looking at a slightly used 660. I know the smaller saws should have around 150 compression. Should the 660 have the same? What would a good healthy 660 motor have and what would the compression be when the saw was halfway thru its life expectancy? Thanks

150 is a good mid life number for the 660.

Thanks Lake, If 150 is mid life, what should new but broke in be?

155 to 170...
