Edited post.. yes an 80. I meant 80 all along..
So after dinner walked back to the spot, owner was there. A lovely south Indian chap. He used to work on a tea estate in the nilgiris and imported this from Japan in 2001. Then brought it over to sri lanka when he retired a few years ago.
In his words 'after 400k miles of the odd oil here and greese there, the engine decided to give up and go home - I should really have made more of an effort'...... So a new, old engine had been put in yesterday and he was just working it a bit.
Why not take it for a drive? Cause the culvert at the end of the lane was dug up.
