In your pictures, the plate at the top of the throttle shaft is a bit different to the standard LME carb. I don't think any of those holes will work well for you. If you look at MH81's pics you can see that the linkage from the governor runs through a hole that is about the same distance away from the throttle shaft centre as the stop on the plate and offset by roughly 180 degrees - that gives it the leverage to pull the throttle open. I think your best bet would be to make a small plate to fit on top of the existing one that would extend out over the carb flange, with a hole drilled in it to take the rod from the governor, more or less in line with the centres of the throttle and choke shafts.
MH81 thinks faster than I do - I apologise for the repetition, didn't see his post!
