In my quest for a cooler engine I checked out the timing of the car and it turns out my damn harmonic dampener timing marks have shifted throughout the years. You can adjust timing by ear and listen to the engines performance but you can’t use a timing light because the marks are about 180 degrees out of view!
One lesson learned is I should have changed out the dampener when I had the radiator out as there is not enough room to remove it now and install a new one. The timing is done by ear and the carb has been adjusted for idle.
