| RE: 360/390 ignition timing and carb setting |

| Al, need more information. Block, intake, heads #Vin numbers? What year car/truck? Two or four barrel carb.? What have you done? What was replaced? When did the problem start? Usually the timing sets around 6 to 8 degree @ 700 RPM, dwell around 24. If you have beaker points the gap could be off, should be set about .015 gap which will give you about a 24 dwell. As for the carb. settings, does the engine miss and shoot the black smoke out during warm up or all the time? Usually the choke will cause a rich mixture if the air horn gap is not right during engine warm-up, but after say 5 to 7 mins the choke should kick off and not be a factor. Also, a vacuum leak could be a problem. Just need some more information and I sure others will respond. RC |
