are you saying the throttle blades are staying open? If so one of two things could be going on here . The bushings on the shaft are sticking, Or cable is sticking in the houseing. Try spraying the carb shaft with carb cleaner and the cable with some WD40 and see what that does. And Get back with us.How does the peddle feel when you step on it? Is it hard? Unhook the linkage and Check by hand. one other question How old is this carb and when was its last Rebuild or cleaning?
hope this helps/starting point }[oooooo]
God doesn't like ugly.
