Check thermostat
Depending on the ambient temperature or the thermostat controls the flow of dilution of the warm or cold air supplied to the carburetor. Damage to the thermostat lead to disruptions by increasing the speed of the engine from cold, increased fuel consumption and engine intake pipe frosting. Check the thermostat on a cold engine. The flap thermostat should rotate freely without binding.
The ambient temperature should be no higher than 20 ?� C.
