Hi Maurice, Max and Paul Max has done a better job here than I could here.
I have one question for Maurice: - where did you get the term "A150" from? I'm wondering whether that reflects the total CC ...
Max, we know the Hurricane Model 125A had a total CC of 150cc and a swept volume of 124cc. BORE: 2.125" STROKE 2.125". [that's the same as the Victa 125 - 2 1/8 inch square.
The 'A' designates an aluminium head. So Max, do you think this engine is, in fact, a Hurricane Model 125A? That seems to be the engine I see.
The complicating factor is the 'A150' thing. I need images of that.
