How can you tell from that picture? Is it because it has a round exhaust port and not an oval one?

No Zeda's have a round exhaust port aswell,but the casting's are slightly different and the engine pictured aswell as the one linked to have the old s**tty fasteners not the better allen cap head stuff of late.

Your A-80 engine is basicly a pre Zeda varient that is a true 40mm stroke,long rod 69.4cc engine.

Thanks for the link to the video. The manual with my kit says A-80, and the listing gave those same specs. Unfortunately, I did not pull the jug before installation, so I missed the opportunity to identify the piston and rod variant because I did not know that I would want to know this, lol. No doubt I will have to go in now and find out for sure.
Can you tell from these photos if my engine is consistent with the "A-80" designation?
I've almost learned enough now to be dangerous and want to go ahead and clean up the ports and match them a little. They sure are ugly as they came cast from the factory!

Fred from CR Machine is the best. He has done quite a bit for our hobby and everyone has been copying his stuff for years. His stuff is expensive but he won't rip you off and it will be high quality.--->https://www.crmachine.com/
When you have some time you should watch some of his other videos on youtube they are very informative.---> https://www.youtube.com/user/turrettooling1968/videos
