I have just bought a Kawasaki 900 stx 2000 jet ski, but am having trouble starting it.
Its a problem to start from cold, is there anything i can add to the fuel system to help with this problem?
Once its warm i have no problem starting it.
I can see that there is fuel in the filter, so this isnt the problem.
Any help or suggestions please?

 

I have a 92 750 Jet Ski. I just had the carb rebuilt but it still won't start. I can pour gas down carb and it will run for short period but dies. Any ideas

 

choke the hell out of it until it hits then let the choke go it should start when it does just let it idle then it should be good.that is they way they are i have one just like it

 

There was a thread on this forum I found but I cant seem to find it now. I had the same problem you are having, i thought it was a priming issue and went and bought a priming bulb but before i put it on i came across the thread mentioned above. I will try and explain it the best I can. Take the flame surpressor cover off the carb. Close the butterfly levers (mine is dual carb) cover the two little holes on the butterfly levers these levers are the choke control. Try to start for about 5 seconds, try again this time pull throttle back about half way. Mine started right up and started the next day as well. It was explained to me in the other thread that pulling the throttle creates vacuum and pulls gas into carb.. Its called venturm effect i think. If i come across the thread i will pos the link. Hope this helps

 

I found the thread, I also had a problem with my choke throttle not closing al the way. I did the below and everthing was find but after a couple of days it started to not start. I reached down and pulled the lever that the cable was attached to and pulled the choke closed and it stated up after about 5 seconds. I need to adjust my choke cable.

RE: HARD STARTING

--------------------------------------------------------------------------------

If you install a primer kit, it would inject a raw fuel ONLY, no oil, unless you run pre-mixed oil all the time. However, I don't think it really would hurt the engine since you are just using it to start the eninge. It all depends how much raw fuel is injected by the primer.

The better or more correct way is to fix the problem. Here is what I would do. Synchronize the 3 choke plates, block the hole on the choke plate, make sure choke is held closed when you turn it on, and, most importantly, you need to open the throttle about 1/2 way while cranking. As soon as it pops. Close the choke 1/2 way and WOT and crank it. This is the best technique to use on all cold blooded Kawi skis that have the cold-hard starting problem.
