I received this jetski pretty much in pieces. i have been able to put everything together and the ski will start on starting fluid for a few seconds then die.
My question is, how does the fuel flow on these things? does anybody have any diagrams or pictures of how the fuel hoses should be hooked up? I have an 87 Kawasaki 650 standup.
Below are some pictures i snapped yesterday. Is there a fuel pump somewhere or how does the fuel flow to the carb?
sorry for the noob questions but this is my first jet ski.
i have added a oil mixer block off plate and the front take i removed after the picture becuase that is where the 2 strok oil would go, but i will just premix myself.

thank you

i found this these diagrams on bikebandit.com that answers most of my questions. i guess i didn't know that these had fuel pumps but it sure does make a lot more sense.

a new question i have though is how to prime the fuel system. i will try searching for that information now.

hi there... the fuel pump is right in front of you on the 2nd pic also it should have diaphrams on the carbs to help the fuel through make sure there is fuel in the tank and fuel is switched on.... try covering the air intakes to choke the engine while starting you may also have a blockage some where might be best to get a workshop manual and chase the fuel line to see if there in the right place

ps never run a 2 stroke on starting fluid as you will be running very very lean and could cause damage within seconds

thanks for the input. i actually had read on this site somewhere about covering the intakes but that didn't work for me. i also took apart the fuel pump once i figured out that's what it was to check for any blocks. surprisingly the fuel pump had fresh fuel in it, so maybe i'm getting close.
i'm going to fill the tank up instead of the little bit of gas i have in it now to see if that will get it going.

there are screens on the pick ups inside the tank also a small gause type tilter inside each carb might be best to strip carbs and clean them

thanks, i will plan on pulling the carb and looking at that as well next time i get a chance to work on it.
i have rebuilt several of my dirt bike carbs in the past so i assume it shouldn't be too difficult. we'll see how it goes once i get there.
i will also look at the pickups in the tank as i have not done that yet.
