G'day Tomkatoz , wce and Tyler
This Carby is a G2 ,normally not worth fixing as the metal flag is heavy and wears in the shaft and the governor
gears strip,mostly all got replaced years ago with the G3 but even now people recommend replacing the barrel and carby to G4.
https://pushmowerrepair.com.au/identify-victa/victa-70-80-series/I personally would not bother fixing the G2 ,I would just buy another mower for parts with a G3 or G4, people
are always giving them away.
