Starting issue 96xp tank vent?

[Brprxt215]

So I’ve had a starting issue all season with this. I have finally replaced almost everything in the ignition system(agm battery,solenoid,rectifier, oem starter) I am still having trouble starting it after it sits overnight. It’s almost like the fuel is leaving the fuel lines( all brand new) and draining back into the tank? There is no fuel in the bottom of hull but does have a mild gas fine smell all the time. Is there check valves somewhere that could be sticking? Someone mentioned to me to check the tank vent lines. What exactly would I need to check and do to fix it? Thanks in advance for the help!

Could be flooding on you due to carb needle leakage. Are you leaving the fuel on?

I’ve tried leaving it on and leaving it off. Really no difference. Friday morning I took the vent hose apart all the way to where it exits the hull I pulled the check valve off and blew a bunch of brownish gunk out of the line. Put it back together and seemed to start up after only about 10 cranks or less. I ended up taking it out in the lake that evening and rode great wave hopping for about 30 mins. I fell off twice during the ride and got back on and started first click of the button. Got back to load up and put it on floating ramp while I grabbed the trailer. Went to start it to drive on trailer and it won’t start at all now. I have to look into it Monday when I get back to town. :/
