I'm not a lawnmower man I'm a vintage motorcyclist but we share a common interest of early Villiers engines.
Up to WWII Villiers motorcycle and industrial/ lawnmower engines were just about one and the same. They diverged wildly after WWII but up to 1940 were very much brothers under the skin.
At present I am researching the original Midget engine. The one that came out in 1931. The motorcycle version with engine number beginning CY is well documented and I have no bother there but as the only spares that pop up seem to be ex-lawnmower I want to find out more about them. For example, Midgets were made with engine prefixes CYA,CYB, CYB and even CYZ.. Has anyone any knowledge about these versions? I've also seen photos of lawnmowers with the Midget engine mounted up right rather than the usual forward slope. Are these exactly the same?
You see my confusion. Can anyone point me in the right direction? Is there some all embracing lawnmowere book that tells all?
Can you help.
