What the hell...I cleaned the jet and the jet holder, and everything you told me to clean Ron...I soaked them all over night in carb cleaner. But it still runs like shit..It will start, but as soon as I let off the throttle it stalls...I don't know what could be wrong..I even tried to run the moped without the exhaust(like in freds guide) but it stills runs the same not a big difference..well the difference is it is 10x louder. Either I can fix it myself or I have to take it to my local moped guy and let me fix it and tune it up for only $120. Anything else it could be..??
