Started a few tests this morning
1.. While ideling i removed spark plug wires from each plug one at a time and could not really hear any change in how motor ran.. Surprisingly ideled smother and steady even with one plug wire off???
2.. Put a nail in top of distributor cap coil inlet and then coil wire to nail.. When ideling i slowly moved coil wire away from nail.. Spark was yellow in color.. Very thin spark from wire to nail.. Spark would jump 3/4" or more
New internal resistor coil, points, condenser.. Which to swap out first?
