Rebuild it, of course. It's an easy DIY job.
I rebuild my carbs every third or so ignition tune. It's a cheap, easy job and the engine runs so much better, consuming less fuel while making more power. It may seem like a daunting task to the beginner but after the second time you'll be an expert and will be able to do it in under 30 minutes.
