At the end of the paragraph before the one you've highlighted, it says "The solenoid on the other hand doesn't have the ability to withstand a doubling of the operating voltage for too long...and so it should be replaced with a later 12V type. I believe these are physically compatible"

In other words, exactly what i suggested in my previous post!

Just for clarification, it is an inertia starter with a separate solenoid and not a pre-engaged starter with the solenoid piggy-backed onto the starter motor body?

As for using a dropping resistor for the instruments, have you considered using an LM7805 5V voltage regulator with a couple of 1N4001s in series with the common (0V) leg to give 6.2 - 6.4V?

Much nicer than DRs for each gauge and more reliable with less heat.
