1996 SeaDoo GTX will crank but won't start. Help..

[jusdavis528]

I have a 1996 Sea-Doo GTX with a new SBT engine that has never been used on the water. It has about 5 minutes on it. I installed the engine and was able to start and run it while flushing with the garden hose. I turned it off because it was idling too high between 4000/5000 RPMs per the tach gauge and I was going to locate the idle screw and attempt to idle it down. After locating the screw I noticed it was idled about as low as it can go but I have been unable to start the ski since. Water was turned on immediately after starting the ski and turned off immediately after I turned it off.
What I know:
-Emptied gas tank and added new gas.
-All fuel lines replaced.
-Selector has been cleaned and I have confirmed its clear.
-Carburetors were just rebuilt and are getting gas (has been primed)
-Replace spark plugs NGK BR8es and confirmed they are getting plenty of spark. Tested them with the old plugs installed.
-Plugs are very wet with black liquid
-Tried starting by adding fuel to the spark plug holes with no luck.
-Starter has been replaced and is turning the engine with plenty of power.
-I haven’t been able to test for compression yet but seeing as how its brand new I would assume it’s good.

Please help,
Thanks

Update.
Well I tried to get as much of gas/oil mix out the engine by removing 1 sparkplug at a time and cranking the engine. This did squirt out quite a bit. I also took the carbs off and cranked the engine and a bunch of mix began to pour out. I felt sure I had removed enough to start the engine but it still wouldn't start. The plugs still look pretty wet after attempting to start. I even tried a gas oil mix in the cylinders but it still wouldn't start. Thanks again for your help.
