Top cylinder is 125, bottom is 140, is this something to be concerned about? This is just outside the 10 PSI or 10% commonly considered to be acceptable. I've checked it 3 times, ran it for about an hour or so in the tank, still the same. The motor has been used but not a lot recently. Should I do a decarb? Leave it alone? It is running good, starts right up idles good. I have not had it on the water yet.
Is there a preferred decarb method? I have been using a full can of Seafoam in 2 gallons of mixed fuel and running the whole 2+ gallons through the engines, it seems to clean the pistons when you look with a bore camera.
