Yeah I've watched them both now, good little clips to help diagnose the problem.
Mine's sort of ticky/hissy and it's getting on my wick a bit, I think it's a mix of both the engine noise and the exhaust tbh. I think I'll be prioritising this over the FSRU next year, going to have to get Christmas and that business out of the way before I can sort this problem out really as I imagine if it's not the plugs then it's going to be a costly experience.
I don't think it's anything major with mine but it's just irritating me that's all.
