Kawasaki engine issue.

Kawasaki 17hp was running last week beautifuly! It sat about a week and now it won't start, there is no fuel getting to the carb I realized.
Replaced the fuel pump, fuel line isn't clogged, can blow back into the tank with no restrictions, does not want to blow into the carb, it will fire quick if u put some fuel directly into the carb, the fuel tank does leak fuel if filled above the pick up on the outside of the fuel tank
Im puzzled and looking for some help, Thanks

Re: Kawasaki engine issue.

If it is a 590V 17 HP Kawasaki are the valves moving. That engine has cam problems and mine it worked on second and did not the next. Roger

It is a 540V, I believe all is working as it should cause if u just kept putting fuel in the carb it'd stay running.

Re: Kawasaki engine issue.

Is there an AntiBackfireSolenoid on the carb. You may have lost power to it or it's stuck closed.

Re: Kawasaki engine issue.

Did you check fuel flow before replacing the fuel pump? After changing the pump? I don't know if the Kawasaki can have the fuel pump installed incorrectly, as some others seem to be able to do. I replaced a Kohler pump, and had to be very careful(in my mind anyway) to be sure to keep the pump lever on the proper side of the cam pump lobe. I don't know if it would install on the wrong side, but I didn't want to find out.
If you have not done so, it would be worthwhile to check that the pump is delivering fuel to the pump outlet(carb inlet). You could have a non-functioning pump out of the box.
If you loosen the float bowl fastener, does fuel leak out? If not, check backwards towards the tank from there. If it does, the main jet could be clogged or if equipped and as noted above, the ABF could be blocking flow. You should be able to hear the ABF make a slight noise as power is applied/removed via the key switch or jumper wire.

Re: Kawasaki engine issue.

Ran fine one week, won't start the next.....Just my guess: Sure sounds like the carb bowl isn't filling if this engine is carbureted. The anti backfire solenoid inoperative, or the float valve is stuck shut. Not hard to check both by removing the bowl with careful inspection of both for proper function and movement.
