G'day Norm,
Yes; if they have changed the jet to the LM type, and put the G4 'spray tube' back in loose, 'cos the equivalent LM type tube won't fit in the G4 body, it would always run severely rich.
However, the G4 jet and tube combo can be used in the LM body, and Victa sold LM bodies both with and without the pressed-in LM type tube, under separate part numbers.
These mix-and-match options have probably resulted in the creation of more than a few hybrid LM/G4 carbies...
I have only one two-stroke Victa here, a 1982-3 Mayfair Ute 160 full crank. So most definitely an LM carby, but it has the idle speed adjust knob!
