Gosh this is mega confusing. Those service bulletins are tough to follow in parts.
My G4 is going to have to be given the forensics before deciding what bits to chose for final assembly.
I notice it's poppet valve has no abc markings, so does that mean you just put it back in any position?
That's correct. The marked poppet valve is the late LM type, IIRC introduced at the same time as the 'turbo blade disc' fitted to the Vortex series, among others. See p.10 of the G4 carby doco in Section 4
