Thanks Stefs,

That is some great info. I have already stashed the engine back in its spot. I will check the front throw for stampings next time I’m near it. I looked it over pretty closely earlier but could have missed something. I’ll have to tear it down at some point anyway. I’m torn about what to do with it. It is a cool piece as it is but could also be great with a larger bore and stroke.

Thanks,

Jason
