Trying to diagnose a WOT issue, I can only get the motor to turn about 3300 RPMs. Other than not going over 3.3k seems to run good. Starts right up
I checked the compression, 3 cylinders have 170, 1 with 160. So far I have rebuilt the carb( When I rebuilt the carb, I reused my old float because I didn't like the float I bought, the measurement marks were off from the original and the mounting holes were too small causing it to stay open), added a fuel filter/separator, drained the fuel tank, new fuel pump, checked fuel system for air bubbles/restrictions, changed cap, rotor, wires, plugs. New, 4-blade 17 pitch prop. I checked the timing yesterday in the water, I set the base to 1 or 2 degrees BTDC, then it advanced to over 14 after I took it out of base mode, but then would only advance to about 22-23 at 3000. Oil looks good...
So, these are what my plugs look like after running it yesterday for about on hour on the water. Am I running lean or is this water getting into the cylinders?
The boat is a 1995 wellcraft eclipse 182s
Engine serial number is 0F748259
