During normal operation, that Schrader valve must be in the "run" position, which is parallel to the length of the solenoid. Was it the cover or the Schrader valve that was cracked. Did you replace both?
Yes, Both were replaced. I was looking at the parts diagram and noticed the float. I was wondering if the needle was stuck and somehow it was getting fuel just enough for it to hit and quit. I pulled off one of the fuel lines going to the carbs and hit the starter to see if I was getting fuel. It had a good flow, so a stuck needle was rules out. I removed one of the drain plugs on a carb that was easy to get to and it had fuel also. I checked the plugs and all looked good and were wet.
I put it back together and it started and ran and ran and ran...I started it several times yesterday and it seems to be fine now. I hope to take it to the lake today for a short ride to check it out. I am now just trying to figure out what changed to correct the problem.
I've had I/O boats for years, the outboards are new to me and it is taking a bit to get use to how it all works.
Thanks to all for the information and help, Maybe I can pay it forward one day and help someone else.
