Hi. I'm in the middle of pulling apart a G4 plastic carburettor and have a couple of old LMs lying around and would like to know what components are interchangeable, apart from the float cap, needle and float?
I have already found the metal plate that sits on the diaphragm is very rusted and would like to know what other bits I can swap in case I discover more worn bits.
Would I be better off just trying to rebuild an LM and fitting that to my 500 twin instead?

Ahh, if only victa had kept producing the thumblatch catcher series, they would be in better shape today!
