Points look square and new…… I wonder if it just got a “bench test”. The story is it was sent to a dealer as a warranty replacement and never installed. I will pull the cam cover at one point and see what the cam and rockers look like.

Any other suggestions?

Wondering why it has intake rubbers and clamps for the carbs….?

T do you think it’s  a take out instead..?

The way the wire is cut…?

Honestly don’t know. Could be. Will have a look and see what the cam/rocker wear looks like. Maybe pull the pan too?

Where as the motor has stamped vin, I would suspect it was a warranty take out for some reason and would probably want to tear it open to do a close inspection on it. It could be on the power side or the out put of the transmission.

I wonder if you contacted Honda warranty claims if they could do a search on the vin to see what was the reason for it being replaced.

Stu….. Honda started selling Civics here in 1976. There were about 10 people in the “Auto Division” and 2 or 3 distributing the motorcycles. I’ve tried in the past, with no results.

Understood. 1976....pre computer and no input to the computer programs. Hard copy files only and most were deep sixed long ago even if the dealer is still in business.

T do you think it’s  a take out instead..?

The way the wire is cut…?

+1...def does not look like a "new" motor.    Do you happen to have [or can borrow] one of those borescopes to look inside?

I have an old one that may work. I think the cam and rocker gear might tell a story too? No use for it, bought on a whim!

I thought about putting it in a golf cart. The challenge would be reverse gear and adequate cooling……
