Don't have any help for you on the initial setting for the fuel and it sounds like you may have fixed the fuel starvation issue.
If you are still having trouble with fuel starvation you might check the check valve for the fuel vent line is working properly and that the vent hose is running straight from the side of the hull to the tank, is not kinked and does not have a low spot where fuel may accumulate and cause a venting issue. Also that the vent on the side of the hull is not plugged.
Hope you get it straightened out.
