I would not expect it to in that case, but it wasn't clear the details of the problem. You could still confirm though, to at least rule that part out. Usually high rpm is related to air (either choke or vacuum leak). One other possibility could be the centrifugal timing advance sticking.
Have you tried blipping the throttle at a stop? When you shut the vehicle off, does it restart and idle down?
Unfortunately I'm not versed in Qjets to know how they specifically could contribute.
