Bonjour Benny,
Well done, I also suffered a bit before beaing to start mine 
I note that your switch button has not the same direction(?) and mostly your engine is musch faster than mine :
Yes, the initial mixture settings did indeed cause mine to run similar to yours. After a little tuning, and running 3 tanks of fuel (Coleman white gas, Marvel oil 50:1), I thought it ran better and had better throttle response with a bit richer mixture.
I see no smoke on your video, did you add a drop of oil in your gasoline ?
There is smoke, I think it is just the lighting.
And Jin's answer to your idea :
I like the little Volkswagen. I'm thinking maybe speedboat, if I can find a suitable hull
