1980 kawasaki 440 standup JS won't start...

I recently bought a 1890 kawasaki 440 jet ski. The guy said he had had it for a year and never had any issues with it. With that information, and a test ride I purchased the ski. I got it to the lake, drove it to a gas dock were I filled the tank up with a 40:1 mix with 91 octane ethenol free gas. I hoped back in the water to go and figure out how to drive the thing and it would not start. I killed the battery trying to get it started so I left it at the dock and charged the battery over night. The next day I went to start it and couldn't get it crank. When I pressed the start button it would only click. After some research I tried tapping the starter with a ammer and got it to crank. I pulled the plugs and tilted it on it's side and crank it until fuel stopped coming out of the spark plug holes. I arched the plugs to see if I had fowled the plugs and I was still getting a good blue spark. After that did not fix the issue I went ahead and replaced the plugs just in case it wasn't sparking strong enough. Still not start. It has good compression, has spark and it has the choke to primer conversion which I used to prime it and still no start. I have no idea what could be the issue. Could I have messed something up in the carb when I filled it up? I'm getting frustrated because the ride to the dock was a ton of fun but it has been a week since then and now I feel like it will never run... I would greatly appreciate any advice. I'm really hoping its a simple thing that I have overlooked. Much thanks and look forward to hearing from someone.

You have carb/fuel delivery issues. Pull and clean the carb(s) and replace anything needed replaced. Your needle and seat are gonna be at least one of those things.
 
It sounds like you flooded it, alot. One thing that is a constant struggle for many running the round body bn38 carbs is that residual pressure in the fuel system can make the carb leak fuel into the engine. This can happen right after riding or for the ski gets hot in the sun pressurizing the fuel and it leaks in the carb.
A rebuild kit would probably be a good idea like kny21 said.

Did you actually check compression with a gauge or does it just sound like it has decent compression? Sounds like a dumb question but those are notoriously hard to start when compression isn't up to par.
