My 85 305 powered K-5 needed a new carb so I bought a carb of a 86 model not realizing that an 86 was a computer controlled carb. I took it to a local carb shop and they said it wasn't a problem so they rebuilt it and installed it on my k-5. It runs good, just deisels bad when you shut it off. I took it back and the guy said it deisels because my truck doesn't have the computer connection it needs to work the carb right. Long story short I will never go back there. Are they right am I just SOL with this carb or can it be made to work?
