Scag Kawasaki Water cooled cranks no start

I have a 61 inch scag turf Tiger I bought used about a year ago. its got a kawi  EFI water cooled engine in it, I'm not sure if its a 29hp or 31hp.  I went to start it this spring after is sat in the garage all winter and it wouldn't start.  Turned out the fuel pump was not running so I ran a jumper to it so it runs when ever the ing is on. I ran it a few times since then with no issues. I left if outside for a couple of weeks and went to start it and the battery was dead. So I charge it up, now it cranks but no start.  The fuel pump is working, I can hear it and if I pull the fuel line from the throttle body and turn the key on it pumps gas out like you read about.  It will run if I spray starting fluid at the air cleaner so I know it has spark. It appears the fuel delivery is not working. I've disconnected almost every wiring plug and cleaned them.  the ECU is the only one that looked nice and clean with grease on it.   I don't want to throw money at an ECU if that's not it.  Any one have any ideas on additional trouble shooting?  thanks

    As your getting fuel at the carb fuel inlet with no start, but it runs on spray, the carb itself is clogged up.
    Could be varnish, could be the float needle stuck closed.  
     
    If the carb has an anti backfire solenoid on the bottom of the carb (shuts off fuel IN THE CARB, when the engine is TURNED OFF.   Turn the ignition on and off and feel the solenoid.  You should feel a slight clicking.   If no clicking, check the 2 wire plug for 12 volts when turned on.   That solenoid will varnish/get stuck closed due to old/varnished fuel...
     
    Pulling the float bowl will give you a visual if it's working (it sucks in when powered up)
