That video was great and brought back many memories from hearing that engine sound when it started. I swear I could still smell the diesel exhaust after it started in that video.
The only difference in the Lister in the video and the one my father had was the one in the video was a 2 cylinder and the 12 and 3/4 he had was a 3 cylinder. After it was pulled from his boat it was in our shed for a few years until myself and a buddy pulled it out and took the engine down and got that old Lister working fine again. We used it for an old sawmill for a few years after that until it completely died after which we replaced it with a 13 HP 2 cylinder Lister.
I used the old manual crank to start that old Lister many times and got a few cracks on the fingers too if I didn't get if off the crank fast enough.
These old Lister's usually started quite easily when the weather was warm but when it was really cold and the base oil was really cold they were quite hard to start sometimes. Some of the fisherman here would just leave their Lister's running the entire night in the winter when it was calling for extreme cold and the forecast was good enough to get fishing again the next day. The great thing about those Lister air cooled diesels was the amount of heat it generated in these winter months which felt great. My father had a shelter on his boat and it was quite warm in there which was nice especially during those cold winter days.
Yes even though it hasn't really been all that long ago it does seem like a lifetime ago now once you start talking about it again and the memories keep flooding back. It seems we both had very similar childhoods but that's not surprising since we both grew up in outport NF.
