The black knob above the pistol grip is actually the fuel cap.

Yep, just like my ST-80. I think the top engine models that replaced it were a step backwards. They were more cheaply made and the booms were quite flimsy. Also, the flexible cable drive sapped engine power. Echo made one like this too but I have never seen it in the flesh.
