2000 Rx Carb. unlikely Problem shortly before Santa Claus-Boarding

[sirhiss]

Hello
I've got a unlikely problem with my 2000 Seado Rx Carb. Ski.
I tried to start it yesterday but it didn't starts..
so i tried a lot of crazy things and no theres the Problem:
-If the fuel lines are connected correctly it doesn't start.
but if I put of the Fuel line to the carbs and spray in some fuel with an medical injection.. it starts and runs fine..
-And if I pressurise the tank by blowing into it, the fuel quickly flowes out the hose ,coming from the fuel valve.
^^is there no degassing?

And now time is runing because Sunday is Santa Claus day and the ski has to run then.

Sorry for that horrible English
and freeeeeeezing greats from Germany

no fuel to engine

Determine if your fuel system routes, or your carburetors fuel pump is failed. It could be something simple in the system, like the fuel separator filter bowl is loose or cracked, allowing air in the suction side of FP. Selector turned to off or clogged. A disconnected line. On the Mag carb, the pump diaphram could be bad, or vaccumn line
from lower case is loose, or clogged.

Try this: take airbox off, remove the supply & return line from carbs and put supply line end into a catch bottle, and airchuch lightly some air into the
return line. gas SHOULD flow into bottle if fuel system is good. Re-attach
the return fuel line. Its handy to have a helper to watch for gas leaks.

Put a very short line onto the carb supply nipple and other end into a very
small amount of gas in a cup. Crank or start, motor SHOULD drink that gas
if all is well with the carb pump. Use safety discretion for this test.
