There have an air leak between the carb and the cylinder and/or the head and cylinder. Old hard / cracked rubber fittings and O rings are usually the problem. When extra air gets into the system it leans the fuel mix and the high idle is the result. It also means the engine runs hotter. Also, cracked or broken reeds can be a source.

i cleaned the carb on the bike and put it back together and now it is as if the float is stuck open and is just dumping gas out of the carb all over the ground.
