I have a problem with my 86 4AC where at a certain position of the gas pedal, it feels like a large fuel cut to the engine. I've been asking around auto parts stores and most of them told me that I need a carburetor rebuild. What do you guys think it is? I'll trust the information coming from here much more than the autoparts stores cuz yea...this is Toyota land of the net and those stores are used to seeing riced neons and foci. If it is a carb rebuild, do you recommend making it a DIY projec t or have a carb specialist do it? Thank you all for your time and patience.
