I don't know about "stock", but mine were always about 110.

They don't usually set a compression reading.
There is too many differences in guages.
My guage (125$) will read different than yours.
The results should all be within 10# of each other.
I have a Force that reads 150# all three cyl.
Had a Merc 225 that was around 125# all six cyl.
So look at the comparrison between the cylinders.J
