Not sure if this video is a comedy, a satire or a horror story.
When he took the cold chisel to the starter motor pinion gear, I though "HORROR".
But, he got it spinning.
When he ripped and I mean ripped the gearbox off the engine, I thought, This is a joke.
But he got it off.
When he poked the wire into the manifold cooling jacket, I thought, Basil Faulty.
But he got it unplugged.
Then when I read in the comments what he plans to do with it.
I thought, Someone is in for an unpleasant surprise.
Hint. A couple of coats of Yanmar grey and then......
Anyway here it is.

That was excellent, Thanks.

That is a huge tribute to Japanese engineering!
The Tsukaguchi boys can be proud!

Holy Mother of Mercy!! That they got that engine running speaks volumes for those little old Yanmar engines.

Thanks for posting Gary.

My favourite bit is when he takes off the water pump.

nice work , the easy part will be cutting the tree away that had grown around the rigg ...
