I need help, jet starts only the first time

[blackmind]

Hello, I have 2 blasters with practically the same problem, it is not a carburetor, the repairs were changed, the problem is as follows:

The jet does not turn on, only if I put gasoline directly in the carburetor, then it turns on and works until it turns off, if I turn it off it does not start, even putting gasoline on the carburetor again it does not turn on, it seems that something heats up, but I cannot identify what it is , does anyone have any ideas, my christmas and new year will be out of the water :/

I suspect you have leaking needle and seats. (and likely also the one way air valve on the fuel tank is leaking.... ....first start and run with fuel in the carb means fuel system is not primed and engine gets enough to start and prime the fuel circuit......second start the engine is flooded from leaking seats......do a pop off pressure test on both carbs to validate the needle/seats.
I don't think its electrical as you say the ski runs fine the first time ypu go out there.....meaning that heat or water is not killing the stator / CDI or coil.
