So i change my spark plugs a nd took her out for a short ride i dont know maybe 60 70 miles when i got home she wasnt running right i pulled the plugs and they where black does this mean my carb needs adjusted or am i looking at more Serious Problem

 

Most likely running too rich, carbs need adjusting.

 

Did this happen all of a sudden....?

Could you have left the enricher on for the ride....? Maybe it's sticking in the on position...

If the enricher is working properly I would verify good spark, try adjusting the carb, and if adjustment didn't work, remove the carb to tear it down...

Has it been awhile since last carb rebuild...?

 

Not unheard of to have a bad new spark plug right out of the box.
