Big Day – – thank you for all the feedback.

Very light rubbing on the crankcase journals. No rubbing on the crankcase faces.
Using oil on pistons for lubrication.
Taper pins – – ok – – full disclosure. Used a fine file to remove edges of the pins. Does not affect the pins when the crankcase body halves come together.
Rings were included when pistons were inserted into the cylinders.
Paint on the power head. Purchased a new Iphone this week and was unaware until the videos were posted that they would be converted to black & white. I have fixed the settings so the color is true. Some things tell me this power head was not taken apart – – the color of the paint, no scratches, paint on the screws was aligned with the paint on the crankcase. Some things tell me this power head may have been taken apart – – the crank rods are different colors, there are small black washers on the cap rod screws for the top cylinder but not the bottom. The top piston has some carbon and a tiny bit of rust on it, the bottom piston does not.
Engine is new to me and I have not ever had it running. Power head was stiff when I got it, originally thought it just from sitting.
Rebuilt the gear case and the drive shaft can be turned in forward, neutral and reverse with hand pressure and a wrench to grab the spline on the drive shaft.
There is a photo of the connecting rod caps. They are marked (as when I opened the case) and the alignment marks line up.
This is only my 3rd rebuild and I’m not offended I’m learning from the suggestions.
