I have a 01 zuma 50cc scooter. at first it would start right up but after riding for awhile it would not start with electric start(turned over fine but wouldnt start)you would have to kick start it So i put new spark plug in it. did not help. after a while it got to be where you had to hold the throttle wide open and kick it to start. so i thought it was flooding and drained the bowl on the carb now wont start at all, the bowl is filling back up. i am out of ideas plz help
