EG8 carb has a auto-choke mechanism attached to a electrically operated bi-metallic coil spring and a choke opener pot. Before starting the cold engine press the pedal all the way once (to reset the fast idle mechanism) and then take your foot off the pedal and crank the engine. It should start and rev up to around 1000 - 1500 rpm and then slowly come down to 800 - 850 when the engine warms up. If this happens then you have nothing to worry. If not you need to get your fast idle mechanism diagnosed and properly set.
