sorry for the delay post but just back from 3 weeks vacation and finally had time to install the manual fuel shut off. all went as planned, had to cut off one stud that was for mounting the factory auto fuel filter/cock assembly and drill out the bracket to mount the new manual fuel shut off valve, worked like a champ!!! thing runs great again, shouldn't have any more problems with that any time soon now, shoulda done that from the beginning and i'd be 50 bucks ahead with no down time. took about an hour to do it all, took my time and drank a beer while installing the new parts. hey what is the line that ties into the muffler and where does it go? its rubber from somewhere under the scooter then metal to the muffler, can i just cut all that out?
