my speedfight started running irregularly and stalling when I cut back throttle I was told it needed new carburettor however two new carbs later and its still doing it. It starts okay but it wont let me throttle for a few minutes-only idles and when i eventually take it for a spin it only goes so far before the throttle dies and will stall unless i keep up the revs. I need to let it sit for a few minutes before it will start again please help!!
