What made Victa develop this more bloated design?
I suspect it was a combination of cheaper production and more modern hi tech looks to get the customers in. The T bar throttle was a clever way to remind people of the t bar automatic in a car which was taking off at the time, particularly on smaller cars.
It was cheaper to make!
Even pressure die cast zinc alloy carby bodies require some finish machining, and the G3 had quite a few other machined components.
Contrast that with the G4/LM; the only machined components are the main jet and the brass needle seat.
