Oh yes - of course - good ole Aussie ingenuity - Now then were the following invented?

Actually - back to the original subject - I had a DA50 once that didn't have a choke. It was the first one I owned and I bought it used. It was a bit of a problem to get started for the first start of the day, I ended up retrofitting a carb with a choke.
