a. The fuel injector control tube assembly is mounted on the cylinder head and consists of a control tube,
injector rack control levers, a return spring and injector control tube lever mounted in two bracket and bearing
assemblies attached to each cylinder head.
b. The injector rack control levers connect with the fuel injector control racks and are held in position on
the control tube with two adjusting screws. The return spring enables the rack levers to return to the NO-fuel
position. The injector control tube lever is pinned to the end of the control tube and connects with the fuel rod
which connects with the engine governor.
