One thing I notice in your photo is that the needle valve limiter is still in place on your engine. This has to be removed to get a full range of adjustment on the Evolution engine. I have to many engines to mention, but the Evolution I have runs as good as any, but since I have many Airplanes that this engine could work in, and several requiring different engine positions, I removed the limiter first thing so I would have a full range of adjustment on the high needle. I have run mine in several different positions with never any trouble. The only thing I ever had to do was reset the needles with the limiter off. Just something to think about. Good Luck.
