My machine seems to prefer to choose a slow angle because of the increased efficiency of the intake. But I wanted to know what standard conditions were like, so I drove about 180 km in standard conditions. Throw is not good at all. Fuel tone is too thick. The engine was started with this set to a slow angle and with the fuel mixture set to a lighter setting. The engine fires easily and runs lightly! Oh, I should have chosen the slow angle from the beginning. There was no need to try the standard. Idling stabilizes crisply at 900 rpm.
