Check to make sure that the slide isn't sticking open.

also check the jubilee clips are done up properly, not too tight or you may cut a hole in the rubbers. also, if you have taken the reed block out, you need a new gasket, its not worth the risk using old gaskets. it might be sucking in air from somewhere.....

My bet is that the slide isnt seated properly

On some carbs you can put the slide in backwards, that will make it rev very high. How about your idle adjustment screw, is it turned in to much ?
