I've had a (2016) Super 8 50R (Agility 50 engine) since it was new. Now about 3400 miles on it now. It has been tuned up recently (new plugs, valve adjustment, new air filter, oil/gear oil change, new battery). Ever since new it starts immediately or will start immediately if I turn it off and turn it back on... also idling perfectly. But if I've ridden the scooter and park it for a 1/2 hour or hour, then try to restart I have to give it throttle and then continue to give it a bit of throttle for 10-15 seconds to then have the bike idle properly else it will stall/not start. Once I get it going it runs perfect. This issue has existed since new.
Is this just one of those temperamental 50cc carb things or is this an obvious sign of a faulty device (petcock valve? mixture screw?). I did drill the hole in the gas cap to see if this was causing a vapor lock, but afterwards did not notice a difference/issue not resolved.
I'm fine living with it, but if a simple fix, I might as well fix it.
