Throttle stop/curb idle star screw size or Number
Does anyone know what the throttle stop/curb idle star screw size or number is for an '85 camaro TPI 305CI?? In the past I was able to use an Allen wrench to adjust it. I have star bits but they're not long enough to reach inside the hole. Thanks...Joe

Thanks for the link and info. Are Torx and star bits different names for the same fasteners??
