over revving on my 125

[beana]

just got a new carb for my 125 put it on today but it keeps over revving can anyone help..

a)air leak maybe? check the carb to inlet rubber is seated and sealed correctly - carefully spraying WD40 around it will result in a change in engine note if is drawing air in.

b) check the throttle is returning all the way down.

Also check the idle adjustment is right

Sounds like too lean on the pilot. Wind the pilot screw in 1/2 a turn and re-try.
