Hi all. First of all, I should disclaim that I am NOT any kind of mechanical expert. In fact I'm probably the opposite, lol. There's a scene in my current WIP where my MC (who is a fairly talented mechanic) repairs his friend's car after it suddenly broke down and stopped working. I want it to be a fairly minor problem that's easily resolved. Except, with my lack of technical knowledge, I have no idea what that might be. For context, this takes place in 1940. I don't need there to be a high level of detail, I just need it to be authentic and need it to make sense. Thanks!
