Reason 1: Fuel does not vaporize as readily at lower temperatures. It also has a tendency to condense on the intake passages on its way to the combustion chamber. This requires a much richer mixture to insure that enough vaporized fuel reaches the spark plug. Reason 2: At lower temperatures, it takes more current to turn over the engine due to higher viscosity of the oil in the crankcase. This lowers the available voltage to the ignition system and results in a weaker spark. This means that there is less soark available to fire the fuel mixture. Reason 3: Thicker oil not only causes higher current draw and lower voltage, but also causes SLOWER cranking speed. This produces less air flow through the carburetor's venturi. This results in less atomized fuel available for starting.
