First check the fuse. It should be clearly marked in your fuse box. Also, look at the mechanical linkage from your carb/throttle body, to the vacuum unit that controls the throttle. Look at the vacuum hose feeding the vacuum unit for cracks. My experience is the vacuum unit that pulls the cable on your carb goes bad or the hose has cracks at the unit. Pull the hose feeding the vacuum diaphragm suck on the hose with your mouth. It should not leak and will hold pressure while you seal the hose with your tongue. If it holds pressure the vacuum unit is not the problem. If your rig has no vacuum unit, well never mind.
More details on your problem will help the more experienced people on the forum.
