Carb problems! Running uncontrolably rich...

[LucPro]

So I did a rejet and my gs was running great... Then suddenly my rpms dropped and it is running uncontrolably rich... Any help???

Have  you checked the float heights since the episode began?

A stuck float, or crap under the needle would cause a sudden and extremely rich mixture.  I would also cause fuel to pee out the carb drains if your petcock was left on "prime" after shutdown.
