katflap, thanks for posting the diagram and thanks to spud for the link showing more details of the cooling system. Funny that the thermostat is not listed on any CSC parts lists. Now, if the thermostat is closed we get just a tiny bit of circulation via that hole in the thermostat and the engine should heat up quickly but would be prone to hot spots. At 82C the thermostat opens. We should see two bars before the 'stat opens and then climb to three bars unless there is too much cooling. Even at three bars the engine is only at 176F. I can now see how the engine might struggle to burn off any fuel or water that accumulates in the crankcase, it's just not getting hot enough. A thermobob downstream of the thermostat would divert flow around the radiator while still allowing flow through the engine and thus avoiding hot spots. Looks like it is time for a bit of IR thermometer checks.
