Default Strange issue with running lean

I've been trying to solve an issue with my 97 JTX 270 and can't seem to pinpoint it. It runs borderline OK when I just start it and then gets very lean and it's not the carb - I've rebuilt it and it is clean, new float valve, etc. I also replaced the crank seal behind the stator and put in new reeds. It seems to me that there is either some other air leak I need to find or I have a problem with my gas flow from the tank. I'll take off the tank and check that but I don't think that is it as I get plenty of flow out the fuel hose and have replaced the filter I have in line.

Any ideas? Should I seal up the motor and look for leaks?
