[QUOTE="Pappy, post: 394526, member: 3278"] When you are doing compression on a 2-stroke Johnson or Evinrude there is no need nor mention of opening the throttle blades. Mainly a 4-stroke thing. Not going to hurt anything but not needed. 250RPM is the minimum magic number for a good starting system. Old or bad crimps on the cables are common with this vintage. After trying the starter feel the cables and ends to see if any are warm or hot to the touch and if so, repair. As long as the compression is within 10% of each other, regardless of the number, you will have something to work with. If.....you decide to pull the cylinder heads and at this point, why, replace all water diverters while in there. If that engine or any other older V-4 was overheated those diverters melt, push over, and will block future water flow. [/QUOTE]
