My son's had the bike since new this year it developed an extreme cold starting issue. At +30c it takes multiple minutes to start. I assumed it was the electric choke so i got a new one, there is no change in starting still super hard. I also pulled the plug to check it seems to be a sparking fine. Fuel is also coming out when i crank it over i pulled off a line to check. Is there any other common things i should look for? Once warm it runs great, starts easy when shut off and started with in the next 20 to 30 minutes and has the power you would expect from a 50cc.
Thanks for any advice/help.
