Tecumseh lighting coil and flywheel???

Which Tecumseh motor does this go to? I was told that it came off of an HS40? The shaft hole is tapered and is smaller than 3/4". What year range and motors does this thing go to? Any help would be greatly appreciated. Oh, and I am doing this for a friend. He will see all of your replies and I can speak on his behalf if needed. He does not live in the same state and sent these photos to me via email and asked that I post this for him. Thanks in advance.

I now know that it fits HS40 but is 2.5Lbs heavier than part number 610769A, which is what Rupp used on 4HP bikes. Oh, and it is stamped Tecumseh and has the number 3 stamped as well. Just the number 3. One digit all by itself.
