I'm slowly working my way through my 429 cobra jet (had about 6 months). Noticed from the previous MOT (from UK though not needed it seemed prudent when buying the car) that there is a note saying that the car should be running richer than it is. Haven't pulled a plug yet to see but wondered what the readings are actually saying about the state of tune? The carb is not the original Rochester, it's a standard replacement holley 750cfm 3310 and I have no idea, short of pulling the carb apart, as to what jets etc are in it.
Would anyone know what the readings might be expected to be for a presumed healthy 429 CJ (done 52K miles) and, if mine are too far adrift, what things I should do, and in what sequence, to the car to address them?
Cheers
