Starter keeps turning over/ won't stop

[joekp17]

Hey everybody! I have a 250 cc chinese scoot and it runs great. I only have one problem with it that is annoying. Occasionally when I go to start it, the starter turns over fine but then it gets stuck or something and won't stop turning over. I turn off the key and the kill switch but it still turns over until I disconnect the battery. I even tried to remove the fuse first but that didn't work. I tried replacing the starter solenoid once and I got this same problem so I replaced it again and it happened once again. Any help on how I can fix this would be very appreciated!
