Hi Graham, This is exactly what I was going to write ! We had a nice long trip out yesterday . The ambient was about 30deg C and as I'm running with this waterless coolant the gauge was up at 92 degC ( or 3/4 on the gauge ) and ......

Driving along, making the common mistake of thinking how well it was going, when it started to go off on a cylinder or two, especially at mid load.
Eventually I pulled the plugs and found the front two were white as snow.

.... and SWK started running on 3 pots on the road works section of the M4. It was fine on the overrun but didn't like accelerating. I tried pulling the choke with no luck . So I turned the heater on which dragged the temperature down to about 83 Deg C ( or just over 1/2 way on the gauge ) and normal service was resumed. So this morning I had the plugs out and they were all running very weak.
I reckon in my case it was fuel vapourisation in the hot summer weather.
I've just been out again and its now running fine.
I've got the original rubber carb; mounts, but I do run the high octane shell petrol. SWK is an 1850 btw. I reckon I could benefit from ducting cold air from the side of the rad; just as the 1500's do.
Tony.
