I42... Strange thing is that of all the IC engines I have used, I cannot say that any of them has suffered from carb icing. However I did have a Mower cut out on me one day, and would not restart until it had stood for about 15 minutes.... Ran it a bit further, and again it stopped for 15 minutes.
My diagnosis, after seeing bubbles coming back into the fuel tank, was that it was suffering from vapour-lock, caused by the very hot operating conditions, and the fuel pipe near the engine.
Good job we don't have that problem with aero engines.
