It starts when you pour gas into the plug holes and try to fire it, but won't pump fuel into the carb and keep it running?  I would disassemble the carb again and check to see if it was assembled correctly.  The diaphragm swells when exposed to the air, can get pinched and cause your exact scenario.  Speaking from experience here...

Ok well we got it running last night. It ran but it makes a popping sound and is cutting out. I don't know if I drained all the fuel but I've put about 4 gallons of fresh gas into the tank. Thinking if there was a problem it would be diluted. Any idea's why its cutting out?

Ok thanks! I wasn't sure if it was a special filter or anything. I've rebuilt carbs before on dirtbikes. I just took it apart and checked everything, looked good (a little dirty), cleaned it with carb cleaner and reassembled.

Well its running but it still cuts out. The cooling line from the head was unhooked so I thought I cooked my motor. I used a compression tester and it said 135/140 in the cylinders so I'm assuming thats fine. Its still very hard to start and cuts out. The ski feels low on power but you can still barely ride it. I'll pull the carb and report back. Any idea's?

Also I bypassed the fuel filter and fuel selector. I connected the fuel line directly to the carb from the reserve off the tank and no difference.

Took the carb off again to see what was wrong. I found the problem. I previously never looked into the intake where the reeds/reed cages are. I took a peek in and saw a hanging piece. I removed the intake and one of the reed cages is broken and the reeds are bent and messed up. Looks like I'll have to replace the cage and reeds.

Thanks for the help everyone!

Does anyone know why this would happen? Maybe its not related to the ski sinking?
 
one thing i have learned recently about flooded superjets---once you get the engine turning over and confirm you don't have water in the crank, don't stop there. I did that then let it set til the next weekend and began having starting problems. finally pulled motor, pulled starter and found it had a good deal of water in it and was corroding up fast and was direct shorting. think i ruined one weak battery then melted the positive lead off a second known good one.
