I was give two of these engines and I do not know where they are from. I know that they are .25 displacement, and I can turn them over without a prop, so they are quite used up. So I'll use more castor oil in the fuel. But does anyone know who made these engines. The were on two old well used trainer R/C planes.
Thanks.
