FWIW: I have been sitting with a 1000cc CR9.5 engine in stop 'n go traffic for more than 1/2hr on the motorway at high noon during a very hot summer day (deliberately not using the shoulder to drive on). The oil temperatures (no oilcooler) measured at the oil dipstick went way into the red zone for most of the time (way past 260F IIRC) and I was getting nervous. I was about to use the shoulder and shut the engine down (got cold feet I guess) when traffic moved on. Everything went back to normal soon after.
They can idle for a very long time. I have not used a fan when setting carbs.
Some of the above is fact, some is fiction, some is my personal imagination and some is just simple truth. [me]
