I have recently been rebuilding a 1975 25hp evinrude and when I put it back together I checked the compression top cyl was #140 bottom is #120 I no this is out of spec but was wandering if you thought it might even out after being ran. I put to new set of rings in it and also had to replace the top piston I did not bore the cylinder I thought the looked pretty good but did hone them thanks for any input. Also should it atleast run with this kind of compression.
