Spark voltage is always a function of the total resistance of the coil wire/rotor/rotor to cap gap/wires to plugs, plug internal resistance, and gap. It is very rare that voltage required to fire these combined resistances exceed 20,000 volts. The coil's reserve capacity above that 20K is OK, but no where near 40K. The amount of current flowing through the switch system (points/condenser, or electronic timing system) is going to be around the 4 amp level with most (usable) coils. The issue is either both or one of these: Carb richness may be set too high for light work causing deposits on the plugs The plugs may be too cold allowing deposits to build up even when just right. Adjust the carb leaner, and or use hotter plugs for light work, and colder plugs for tillage or heavy shaft work. JimN
