Oh boy look at that. I just always say that these old Hondas were usually parked for a reason.
Besides finding out what's going on inside it's important to make sure all the surfaces are assembled with oil and grease so that when things get moving there isn't any accelerated wear. Grindings and shavings left behind from the old oil or worn out parts can quickly ruin things inside. Not that you don't know this
Just thinking out loud. I have found some horrifying things inside old engines. It's amazing how I've seen some grown men try and add oil to an engine and expect to start it up! haha
