2004 60HP Carb 4-Stroke Hard Starting

We have an '04 F60TLRC that is real hard to start. So far we have checked the following:
Fuel is new and clean (no water)
Compression 120# on all 4
Spark seems week and erratic SOMETIMES and sometimes it's good.
#1 spark plug is clean and gray/brown
#2-3-4 spark plugs are sooty
Swapped coils from top to bottom to no avail.
Rebuilt Carbs TWICE, disassembled and cleaned in ultrasonic cleaner both times. Replaced major gaskets and "8" o-rings on engine side of the intake.

When it does start it runs alot smoother now, but still hard starting.

Any help is surely appreciated.

Looks like ya didn't want ot help anyway. What wrong with my signature look at your signature
 
I just went through the same problems with my 05- F60.
It would sometimes take up to 10 cranks to fire.
Finally ran a can of Seafoam through 2 - tanks of gas and now it's starting 1st or 2nd time

Hello, I have the same issue with the same engine.
Hard as hell to start, cleaned the carbs multiple times.
Just how do the enriching valves work?

Prime start system enriches the fuel to all cylinders at cold start.
Once running the motor charging system sends voltage to the heater unit and it warms up a wax pellet that pushes a needle into a seat to close off the passage.
 
Seems when I leave it for a week without running, it's difficult to start.
If I go to use it the next day, it will start up fine.
:confused:
 
Ok, for anyone having the same problem.
Pump the ball until hard and then keep pumping it 4 or 5 times.
It seems this helps and usually starts 1 or 2 cranks
