Have you tried changing the spark plug?

A black plug would probably mean a rich burn. it sounds like you could have the float in the carberator set too high. This would cause an over fuel for the engine. You need to keep the throttle opened up to allow for more air in the fuel mix. thus this is why it will only run off of idle. Re check you carberator setting have a good look at the needle and seat.

Your float hight should be 13 to 14 mm from the carberator base mating surface to the top of the step on the float. sit the carberator on a workbench on the venturi end of the carberator this is where the air enters the carberator (hooks to the air filter).
