Yes. (Hence my previous suggestion.)So if the position of the hornblock in the guide is too low and using thicker wire won't work or will provide springing that is too stiff, then I would be inclined to replace the BM wire retainers soldered to the hornblocks with something longer (handrail knobs perhaps).
Jol, this is an underslung arrangement. Putting something longer in will make the chassis even lower!!
Ooops, it's those upside down photos that do it.
in which case, do the slots in the sided oh the hornguides allow enough vertical clearance to raise the wire sufficiently to get the ride height correc? If so, replace the chassis wire supports with some from the LRM CSB adaptor etch, which has several different types. They would be easier to solder in place than adding handrail knobs at this stage. I've added a copy of the drawing from the LRM instructions to give an idea of what they look like.
Still worth speaking to BM though, as they may be aware of this issue and know what is wrong or have a cunning plan to fix it.
