what\'s wrong with my carb? I've got an 85 chevy 3/4 ton 4x4. It has a 350 with the stock rochester quadrajet carb. It's a dog off the line and has no passing gear. If I floor it it slowly gets up to speed and has a bog right off the line. I checked all the vacuum lines and everything is good, new air filter, pcv valve, plugs, and wires. I know it has something to do with the carb. I don't know anything about it. What can I do to adjust it to run better? I'd like to get a new carb eventually but for now the stock one has to do.
