run on with the ignition switch off is usually with these engines/yrs dieseling ...to take the guessing out of it you simply measure the voltage 12 volts at the distributor ....switch on 12volts off o volts ....


with no voltage at the coil and the engine continues to run this is carbon deposits in the combustion chamber glowing causing the fuel vapor to ignite /////no spark needed .......

this is usually an overly rich mixture to avoid detonation .....I would get the proceedure to properly adjust the carb mixture screws ...this means a vacuum guage and tach...check timing first ..and make sure no vacuum leaks before adjusting anything ....

idle should be set to 650 rpm in gear....
