The compression numbers are all over the place. When you disassembled the engine did you mark the cylinders and heads? And did those marked cylinders all go back into their original positions? Was the replacement cylinder the same size group as the other five? Were the heads worked on at all? What condition were the valves in? Did you replace the head sealing rings (gaskets)? Did you replace piston rings? Did you do any work on the cylinders? Hone? Polish? Clean? What do the spigots look like? Did you use a straight edge to check the cylinder heights? Did you check the heads with a straight edge after assembly? If so was there any difference? How much difference? Did you use new copper cylinder base gaskets? Why didn't number 3 cylinder come off?
Any one of the above could be the cause of your difficulties. I'm sure a bit more digging into this will reveal what the real problem is.
Good luck, and I hope the hurricanes stay away.
