Micky,

Get a gas can, disconnect the gas line at the carb, and let a quart run
into the can. Does the gas flow out or is it running slow? Replace the fuel
filter if it runs slow. Reattach the gas line. Ok, you've eliminated the old
gas and the gas line/filter. Try and start it now. If the symptoms have not
changed I'd suspect crud in the carb.
What's the story behind this scooter?
