Just got a puch cobra, it was running fine for about 2 hrs today and then all of a sudden the throttle was stuck on, it wouldnt stop unless i put both brakes. so I killed the moped. I started it back up and it took a min for it to start going but ran fine for a bit. I stopped had a drink. Then I go back to my ped and now it wont start at all. I check the ignition it was fine. and the inside of my tank it coated so I dont think anything would clog it.
