If you're throttle cable is too tight and not letting the slide close all the way THIS could very well be your problem. The threaded part that the cable goes into can screw in and out to either tighten or loosen the slack in the throttle cable, the round "nut" that's on it should be tightened DOWN against the top of the carb to lock the adjuster into place.
Start with the CABLE adjuster all the way down, twist the throttle and if it doesn't return all the way without twisting it backwards screw the adjuster out until there's just a little bit of slack in the cable. Once the cable tension is correct tighten the jamb nut against the carb.
Here's a picture of Norm's pen pointing you in the right direction.
