water in the cylinders - engine won't start

Got a whole series of problems that end up with the engine not starting.

Spring commissioning: changed the points, plugs, condenser, impeller. Started it on the hard, ran fine. Launched, ran it around the marina for 1/2 hour or so, ran fine. One week later, had a lot of difficulty starting it - starter cranked and cranked and finally turned it over. Ran it 4 hours straight - temp at 170 (fresh water) and then down to 150 (salt water). Pressure steady between 35 and 40 psi. After 4 hours, turned the engine off, sailed for 2 hours, attempted to turn the engine on to motor into the mooring, wouldn't start.

Took the carburator home, opened it up and cleaned all the jets, replaced needle valve and seat nut. Installed the carb, cranked the engine over several times, flooded #4 cylinder (forgot to turn the raw water intake valve off). Took off carb, fuel pump, flushed fuel lines. Removed spark plugs, put MMO in cylinders, checked compression (good on all 4), turned flywheel to open intake valves and blew compressed air into all 4 cylinders as I moved flywheel around opened each cylinders' intake valve. Changed the oil.

I believe I got all standing water out of the cylinders. There may be moisture, not sure. Installed fuel system, Set cylinder #1 at TDC, adjusted the distributor until points were just opening, checked for spark at the coil and at the plugs - good spark. Attempted to start but failed.

Tried starting fluid, pulled the carb opened it up and cleaned it again. Drained all residual water from engine through the water pump, blew out the cylinders again, can't get it to start. Seems like I have compression, spark, and fuel but it just won't turn over.

I'm stumped and could sure use some fresh ideas. Any help would be greatly appreciated.
