Flooding. Help!

I have a 88 dodge diplomat with a 5.2L 318 2bbl and it just recently started to act up on me. Every time I start it, it runs fine for about 2 min. Then fuel starts to bubble out of the carburetor and starts to run really rough and the motor gets flooded. After that happens it is hard to start it again. Please tell me what would cause this and how I would fix it.
Thanks. :screwy:

Its time to replace the needle and seat, plus reset the float level, you
can get the parts from your local parts stores

I had a problem with flooding like that on an 88 Shadow, the harness snaking past combustion chamber wasn't grounded.
