Can anyone tell me what kind of compression to expect from a health 1990 Force 90hp? I checked all three cylinders I have 120, 125, 125. :D

Re: Motors and engines compression

you are close, oil slick...If you said 135-140 you would be spot on...but I would not worry, cold motor, battery not quite up to snuff,etc,etc.....the fact that they are even is the important part.
