Its a bugger isn't it....
Sounds like carb icing I used to have on my Golf Mk2 with a Weber.
I would try as you suggest, blank off a bit of the rad, and also it sounds like your "flap" is stuck to the "cold" setting (i.e. open to the front of the car not off the hot air from the exhaust manifold shield.
Can you take off the vacuum pipe that should operate it and suck to see if it moves? Can you free it up by hand?
Whereabouts are you in Bath/Bristol? I'm leaving Gloucester about 1220 and could come and poke it with a stick (I'm no expert but 2 heads might help).
It does (I found out) depend on the weather conditions, I only had it happen 2-3 times in a year. Last night's cold AND foggy weather did it. If it is cold and frosty it didn't happen. Give me a text/call on 07971 661221 if you want to meet up. I have a limited set of tools in the 100.
Bet you looked a right tit pogoing up Brislington Hill....
Have you got the heater thing off the pierburg (not the hedgehog, but a small "button" thing that you bolt/screw onto the Weber)???
