We have a 78 Camaro with a six cylinder 250 in it. It had no emissions on it when we got it and the EGR valve was siezed. I've replaced all of the emissions parts (vacuum lines, EGR, TCS etc). I also replaced the control module, cap, rotor, plugs and the carb.The problem I am now having is that it will not come into the correct timing range or the proper RPM. When I remove the PCV hose, the engine will settle in at an acceptable RPM (around 650) but when I reattach the hose, she wants to bog down and almost stall out. When this happens I get a pretty good fuel odor out of the carb. The timing is way out of top dead center and with the vacuum line to the distributor(HEI) disconnected it still will not come close to what the book calls for, as a matter of fact the closer I get to spec the lousier she runs. I realize that it is not a performance car, but it looks good and it is my sons first car, so any help you can provide is appreciated.
