2000 Seadoo LRV won’t stay running

[JimTex]

I have a carburetor type LRV, you stray a little fuel in carbs and it will turn on but won’t stay running.
The previous owner disconnected the speedometer wires to install a Radio instead. Will the disconnected wires stop the engine from continuing to run?
What are all the things I need to check to get this fixed?
Thanks

Sounds like it’s burning up the fuel that your spraying in and then dying . Electrical isn’t the problem, check the fuel system. What’s the history?

 

[JimTex]

I found also that they bypassed the fuel selector valve and I see one of the gas tank connections block off. I also found the forward carb chock cable disconnected. Here are pictures

Fix that stuff up, if it runs with fuel pit in the plug holes it’s fuel system

Have you rebuilt fuel system? or has it ever been done?

 

[JimTex]

I ordered a fuel/ separator. I tested the fuel selector valve it seems to be good not sure why they bypass it.
Today I am going to check the fuel lines and vent to make sure they are clear and good. I will see in a few days when how it all works when I get all the parts in.

How did you test the fuel selector valve? They have by passed it because they were also have fuel issue and they thought that the selector valve could have been sucking air or partially clogged.

You probably need to rebuild the carbs

 

[JimTex]

I took the fuel selector valve off the Jetski, I blew into the input then I felt all the air come out one of the outputs than I switched the selector and blew again and air came out the other output. I know it’s not clogged.
The previous owner said he rebuilt the carbs. Of course I don’t know what kind of job he did but he said he used Mukuni kit and he explained what he did so it sounded like he knew what he was talking about.

 

[2strokeboy]

if he rebuilt the carbs then you should get a clear tube, hook it to the input on the carb then put the tube in a bottome of gas too see if the fuel pump is working

 

[JimTex]

Will do, thanks

You would need to test the selector with a vacuum pressure to see if is sucking air, just because air will blow through it doesn’t mean it’s good. If you’ve by passed the fuel selector valve and fuel filter/seperator, then it’s most likely the carbs. Before buying a rebuild kit ( I would recommend back to IEM kit from OSD marine) you could take it off, verify that your pop off is correct and that the fuel pump is not leaking , check that high and low are at factory settings and that the right pilot and main jet is in there but might very well need to rebuild it.

So Burt, explain how do I test the pop off and the fuel pump from leaks

 

[burtshaver2021]

Take the cover off the metering side of the carburetor, either buy or build a pop off tester, and apply air keeping an eye on the gauge to see when the needle pops off. To test the fuel pump just apply 4 pounds of pressure. Also when the carb is back together put 10 pounds of pressure on the fuel inlet fitting to make sure the needle isn’t leaking. You can find a great carb rebuild thread here on Mikidymac’s profile and also can find testing procedures in the manual which is free

 

[JimTex]

Perfect thanks

Yw, I forgot to mention to wet the needle seat area with WD-40 when testing the pop off, you will be able to see if it’s leaking at the same time. Best to look over Mikidymac’s carb rebuild thread first. It will fully explain it, and there’s pictures.
