Oh dear
Slight misunderstanding here, I am not be pedantic, but there is a fundemental flaw in Billy's explanation-------. When gas is compressed, it heats up, when it expands it cools (aka refrigerator). When fuel & air mix (in the carb), the petrol evaporates, which takes heat. The heat has to come from somewhere & the carb being metal (says he not even knowing if they are on the SV), conducts heat very easily. When the ambient air temperature is warm (say +5 degrees), there's enough heat to go around. When the temperature is cold (say l< 5 degrees), then the evaporation process still requires the same heat, then things start to get dragged down in temperature, the carb gets to a temperature below the freezing point of water & guess what, the water in the air starts to freeze on & probably in the carb--------- There are times I wish I wasn't an engineer, I'd probably earn more money & wouldn't find myself writing sad E mails!!
