The wifes Scooter is feeling sick today. She said she barely made it
home today. What it is doing. It is idleing fine, but when you apply
throttle it surges up and down ( it is a steady rev up and down, up
and down ) with little to no power. Seems to run steady at low
throttle.

Air cleaner is clean ( acts the same with or without aircleaner.) Yes
there is fuel in the tank, put some fresh in it to be sure. I guess
that leaves me with fuel or carb issues. Any Ideas out there. Thanks.
