2 stroke Derbi GPR50 very hard to start when cold and at random

In the morning when it's around 5 degrees Celsius and at traffic lights I have issues with starting the engine.In the morning I turn on the choke all the way up, and try to start. I proceed to get only stuttering. I'll hold the start button for 5 seconds at a time and do this 3 times. Usually it starts after the third time. When the weather is hot, I'll have no issues with cold starting.And at traffic lights with a warmed up engine I'll shut down the engine to conserve fuel. When the traffic light goes green, I'll start it back up and usually this works instantly. Sometimes though I get the same symptoms as the cold morning start, creating a dangerous situation due to rear traffic. So it's not something I can ignore.Your advice is appreciated. via /r/motorcycles https://www.reddit.com/r/motorcycles/comments/e8sdoo/2_stroke_derbi_gpr50_very_hard_to_start_when_cold/?utm_source=ifttt
