Can't remember if I posted about this engine but I want to update anyhow.
Found it at a swap meet around thirty years ago and I finally decided to try it out.
I know absolutely nothing about it. Country of origin, year of manufacture?
It displaces 6.8 cm^3 (.414 in^3) and weighs around 7.5 ounces.
Starts easily and runs smooth.
Not much power - maybe equivalent to a modern .19.
But, I figured why not try it on a nice light OTS plane.
Anyone have knowledge of this little stranger???
