Hey guys I just finished my 80cc bike kit and it runs good once it starts, tho it takes a while to prime it and get it to start. Once it's going, if I try to slow down the engine will stall on me a die, and it won't start again for a few minutes, idk how to get it to stay idle I tightened the idle screw all the way but it yield no difference. How do I keep the engine form stalling on me at low speeds and while idling? Also would I be a good idea to buy a new spark plug? Iv read on the forms that the spark plug that comes with the kit sucks and replacing it will help it start
 
if the idle screw makes no difference, then something is wrong with the carb and/or the throttle cable

I'm thinking maybe air leak at the carb & cable too tight. When you turn the throttle down, you should hear the slide hit bottom and then feel a bit of slack in the cable.
