Last update: 13/4 2009 Design by Ole Bjerager Moving bellcrank shut-off with activation based on a mini swing-arm. This system looks much like the Forbech 2009 design but there is an important difference. The metal arm that pinches the fuel line is not a spring. It is a free moving part made from soft steel. It is turning around a hole in the center section and the bellcrank is attached to the other end. The small spring on top of the center section is actually the spring that moves the bellcrank and pinch the fuel line. This construction eliminates the bottom plate.		Ole Bjerager
