I was looking at the forcast for the rest of the week and it looks like I might be able to get a ride in on Friday.

That got me to thinking that I don't know how the heated carbs work. I think they heat the gas in the bowl. But at what point does this happen. When the switch is turn on or only starts to heat when motor is running. Is there some type of thermostat that controls all this and at what temp does the heaters kick on.
