PART FOUR - The 3G Bonmows

The single biggest upgrade to the Bonmow occurred with the introduction of fan cooling
to the little Villiers engine in 1956. This would be the Villiers 70cc Mark 3G.

The improvements were widely advertised:-

MUSEUM of VICTORIA Bonmow Leaflet:
The M of V holds a leaflet or flyer in its collection.
This was a simple, one-sided print flyer for the upgraded Bonmow.

I have one of these flyers and make it available below.

FURTHER CHANGES
It would appear that further improvements were made for the 1957-58 lawnmower season.
The first was the repositioning of the carburettor (via a long intake manifold) to the
rear of the engine. At this time a snorkel air intake was fitted. Second, a Villiers
recoil starter was fitted to the engine, replacing the outdated lanyard start.
