So I just got this motor and a 14ft cobia. Ran it for a while and began fouling the cylinder. Replaced the coil and new plugs but when I was putting in the new top plug I noticed debris in the cylinder. I did a compression test and 85 top 95 bottom. How bad is this?i also did the test with the motor cold. Should I warm the motor up and then test it again. Does it matter?
