Whit,
I'm a Yamaha guy:) well Seadoo as well. This is a common problem. You should pop the carb apart. Two bolts, the throttle cable, fuel in, fuel return, and pulse line,,, the carb comes right off. If it is 100% stock there will be two head bolts to remove as well. There is a internal fuel filter that gets clogged with junk. This fuel filter is on the same side of the carb and the pulse line. Some other things you may want to do: pull the fuel tank and clean it out, replace the fuel filter, replace fuel lines. My Superjet fires up right away all the time even after sitting for a while.
Here is a link to a carb thread from a while back:

Joe...........

i would loved to have seen those pics, but all i get are little boxes with xs in them, oh well.

hey joe, i tore the carb apart for the 3rd timelast hight, and the filter was dirty! quick fix! i went in this morning hit the switch... nothing, pulled the tank and cleaned it out, added an in line filter along with a primer bulb. had to spin the crap out of it along with a LONG CHOKE BUT IT DID FINALLY (sorry) bust off, but ran like poo. pulled the carb back apart and found a very small hole in the damper diaphragm. so im looking for a rebuild kit for the 44. does that sound like a problem that would make it hard to start and starve for fuel some times? and thanks for the help man, your golden

If the carb is hard starting it might be that the fuel pump diaphram is worn and stretched out so on the cranking rpms the crankcase pressure is not high enough to get the fuel pumping though the N&S... Rebuild the carb and also check the N&S...

N&S? whats that?

The Needle and Seat inside the carb...

what a dunce am i, come to think of it, the fuel pump dia. did look big and baggy.. i am going to order a kit friday, and i will check the n&s, thanks
