Hey! All: I have a 1968 9.5hp Evinrude model 9822. When I first got it, the upper cylinder compression was 70, lower was 63. I since then replaced the head gasket, thoroughly cleaned up the head cover, after that, the compression raised to 80 up and 72 down.
Here are my questions:
1 Should I be concerned about the uneven compression?
2 If yes, is there any product out there that might restore the compression? I think those white can with blue cap engine restorer are not formulated for 2 cycle engines?
