A hot coil can enhance cold starting capability, but that's about it. And, even that's a trade off, since it can shorten ignition points life.
When Deere made the transition from two cylinder to the newer series engines and tractors, e.g. 1010, 2010, then the 1020s and 2020s, etc. , a "hot" coil" WAS used, how hot I don't know since Deere offers little technical data. But, Deere used a 6 volt coil with a 12 volt system along with various types of resistors. This provides around 9 volts at cranking to a 6 volt coil instead of 9 volts to a 12 volt coil -which gives more voltage potential.
