Changing to premix will lean the mixture because the oil is thicker than gas. Increase the main jet 1 or 2 sizes and raise the needle 1 notch ( move the clip down 1 notch on the needle ).
If the gas line is leaking, it will leak gas out not air in. The carb cover will not cause it to run lean.

You are right an air leak will cause it to run lean. It has to be an air leak into the crankcase or carb mount. It could be a crank seal, cylinder base gasket, carb mount.

Did you unhook the oil injection or remove it? If you removed it, did you plug the oil holes into the engine?
