I recently replaced my friend's fuel pump in his scooter. It sat for over 2 years with old fuel in the tank. I removed the tank and cleaned out what I could from it and had to replace the pump also. After riding for a while and coming to a stop, it is shutting off. I work on diesel engines and gas engines but mainly on trucks and cars. First time working on a scooter. Can someone please help me, or let me know where I can get information to help resolve the issue. I'm new to this forum and haven't searched the site completely.
I do appreciate any and all help that can be shared. Much appreciated!
