Yep, 71. And, the Chiefs are gonna win!!!! (I hope.)
On the wiring, depending on where you connect the white/light blue to the red/light green you may bypass the resistor and you will be running battery voltage to the coil at all times. And the coil will overheat and fail. I'd check to see that it isn't wired correctly and, if not, choose a spot on the r/lg wire such that you don't bypass the resistor.
As for the air cleaner, I once had an air cleaner that didn't fit properly so I know it happens. But the only part I'm aware of that would fix it would be another bottom. However, yours is probably the light weight aluminum bottom and those are hard to find as they frequently cracked. I don't think I have an extra, but will look.
