Craftsman blower 25cc leaking carb

I have replaced the primer bulb and fuel lines on this blower. I cleaned the carb at the same time by spraying with carb cleaner and blowing out any orifice with compressed air. I did disassemble the 'diaphragm' at the base of the carb. Now after assembly, when the primer bulb is pressed, gas leaks from this area. The blower will now start either. Did I do damage or will a new 'diaphragm' gasket fix my issue?
All comments, criticisms, or suggestions welcome....

Edit: This post is about the leaf blower, not the Ryobi trimmer. That's another issue...

I've read that compressed air is a no-no on the 2 cycle carbs like walbros. There is a check valve in the main jet that be ruined.

I think they say the force of the spray cleaner is enough to clean these.. Any time I take these little carbs apart, I always use new kits.. If the primer & lines are rotton, so are the diaghragms.. Find who made your carb & get a kit for it. The manufactures have excellent manuals on their websites.. Pay close attention to the order the gaskets & diaghragms go together & you should be fine..
