It could be the slide sticking, the cables being junk, or even a vacuum leak. You can take some starting fluid and spray it between the carb and the head on the intake manifold on the outside while its running. If its leaking, the engine will speed up as you get to the leak with starting fluid. I would take the carb apart, make sure the slide works properly and the throttle slide return spring in the top of the carb arent bound or missing.
