PART TWO – First Model Vinco 125 The first model Vinco 125 had no assisted cooling and I have found no primary documents about it.
That is odd; given the company’s propensity to advertise.
We have good evidence of the engine’s existence thanks to a couple of examples appearing on early Atco rotary mowers. Maybe that’s the clue … the difficulty of Atco Australia importing the little Atco-Villiers engine. Who Knows?
The engine was a basic 125cc air-cooled loop-scavenge 2-stroke not unlike the first Victa 125 engine. Both used a Wico flywheel magneto system and both had a removable alloy head and cast-iron barrel.
There were differences though. The Vinco has scavenge porting that did not need transfer port covers, and the head and barrel were secured by long bolts to the crankcase.
Sincere thanks to ODK member and Qld collector Paul C who has given us the only detailed images - and commentary - of this rare engine. [see Related Links].
PART THREE – Vinco Fan Cooled Engine The mysterious first model Vinco 125cc air-cooled engine was developed and modernised to have a shrouded cowl and fan-forced cooling. It would also accept a recoil starter.
My best guess is that the engine was developed for a key project – the Vinco Blitz home gardening system of about 1960 [see related links].
The thing is that the Blitz also offered a governed Kirby 4-stroke and that engine seems to have been favoured over the 2-stroke in Blitz advertising.
In fact, the final model Blitz dropped the 2-stroke altogether.
This eleven-page Operator Manual for the Air-cooled Vinco Industrial Engine dates from the early 1960s and it is in poor-to-average condition; with some water staining. Beggars cannot be choosers in this case.
Interestingly, note the only image in the booklet [inside cover] of the engine has been pasted in upside down…
Also note the Victa-style recoil starter. [I wonder what the story is there…]
As always, I make this booklet available to members for viewing or as a quality download.
