An 81 e4me qjet should work pretty much the same as the 4M or M4M QJets. My first guess would be that the linkage or throttle shaft itself is binding. Then a sticky choke.
When this condition is created, I'd recommend taking the air cleaner off and visually inspecting the linkage - is it against the throttle stop screw? If not, why? Is the choke holding it open (you'll see that the choke flap in the airhorn is not "straight up" as one indicator)?
