It seems like it "should" be a fairly simple fix. If I tip the shifter upside down, gravity pushes the pawl into place and I can shift through all the gears perfectly well. It seems like the pawl just needs some pressure on it keeping it in place and without seeing the internals of this section I can't figure out where the pressure should come from/why the existing set up isn't providing any.
there should be a spring on there, I can't help thinking it may be the pawl thats broken rather than a spring. have a look though, if it doesn't work you have nothing to loose by pulling it apart. getting it back together is the hard part.
Appreciate your input.
