Have the subject scooter and had to convert to kick start. That part works but it wouldn't start. Replaced the carb with a newer version. Will only start with starter spray in the carb. Otherwise doesn't seem to be getting any gas. Got spark, got compression, got fuel (converted to a mixture before my time). Just doesn't seem to be drawing in any gas until we spray with starter fluid. Kinda at wits end with this durn thing. Any thoughts?
