I have either a '69 or '70 model 75 7.5 HP motor. The middle digit on the tag can't be read. The number is 281?525 on the tag. Looks like both years were the same. Just recently I am seeing some of these motors with the Lighting ignition and some, like mine, with the Thunderbolt ignition.
What's the difference?
Is one better than the other?
Why did they have 2 ignitions for the same motor at the same time?
