Nice to see some pictures, I knew there was something wrong with the instructions in the workshop page. Perhaps you can get those images put up in the workshop section?

I thought that it must be the case, and I adjusted mine as shown above, using the second index mark to the body index mark. It did smoke a LOT so I backed it off a bit. So, as said previously, it's now using the same amount of oil as if I were running a mixture of 37.5:1. Is it not advisable to adjust the oil injector off further?

I might go to premixing my fuel, as I'd like to run at 50:1 or 45:1. Helps stop the thank from rusting too!
