I recently bought an O.S. 70 at a swap meet for $5 . It had been crashed but only tore off the rocker cover and part of the head casting where the rear rocker cover bolt threads into. Otherwise this engine is prestine, no other damage.
My question is,how do I tell the difference betwwen the 70 surpass and the 70 surpass II. I know it is not the new generation 70.
Please help[
