Wow, what a thread. I believe that Lister engnes from India seem to "all" have quality issues. Even the best from what I can tell. I ordered 3 engines from a less expensive exporter (GTC) and got exactly what I expected with a few additional flaws thrown in for good measure.
So far the exporter is willing to fix the issues one by one and clearly stands behind his product by sending new replacement parts. So, I am pleased, for sure.
The issues are: sand, rough cranks, dings in one crank, 1 really bad rod, sand, sand, rust in 1 cylinder, scores in another, non rotating tappets and bearings need to be changed.
So we clean, polish cranks, change bearings and grind tappets. Not really unexpected at all.
