Point 1: Starting behavior
In the first winter I often cursed when I wanted to start the engine. A minimum of 6 pulls were necessary to get the motor working. After the first summer break it even needed more than 30 pulls. One year later my dealer let me into the secret: The choke lever is faulty designed. After you pulled it out it snaps back a little to a position where to choke is not fully activated.
So what you have to do is pull and hold the choke with your left hand, reach in a yoga-ish way with your right hand below your left arm to the recoil starter and hope that your spinal discs are in a good mood.
Following these instructions you end up with an engine that starts up at the first or second pull.
It's a mystery why this failure has not been fixed even though it is already well known.
