The carbs on these bikes are very "cheesy"...
Don't worry, or waste too much time trying to tune it until the engine is fully broken in and warmed up!

Also, make sure you don't have any air leaks in the intake gasket or carb area.

Sounds like an air leak at intake.. You can check it by running the engine and spraying wd40 near the connections of intake, and listen for changes in engine speed.

My cable delaminated, the inner spiral came loose, all sorts of idle issues from that.
