I just pick this up today for my son. Have to feather the throttle til it picks up a bit of speed and is fine til you let off and then have to play with it to keep going. if i give it a bit of choke while getting going it picks right up. some times just plain out dies when starting out . where should i start?? has new gas, oil, plugs, and guessing good fuel pressure since it runs good at wot . thanks!!!!
pay attention to the orientation of the rubber plugs on the jet tubes when you pull them for a good cleaning. there are air jets on the airbox side that become plugged as well. make sure these are unobstructed as well.
