Originally, the ratio was 20:1, but 32:1 is the most commonly used ratio today. Technological advances in the manufacturing of oils allow for the ratio change.
Judging from the "two spark plugs" comment, I guess the previous owner put in a spark plug where the sealing bolt should have been. One of the holes is for the plug and the other is for a sealing bolt. Some say that this sealing bolt is for compression testing without the need to remove the plug. Personally, I've never removed mine for anything.
If you go to this site, you should see the breakdown for your Odyssey FL250:

Click the "Cylinder" link (first one) and you'll see the plug (#19) and the sealing bolt (#13).
If you want to learn more about these fun machines, go to the Pilot-Odyssey-PitStop and register. Here's the link:
