Stihl combi revving on idle

[Shaunpaul]

Hi, my Stihl 130 combi has been playing up today, instead of idling when trigger is released it seems it's on half revs, so chain/trimmers are still moving. They've not seen a lot of use and are in excellent condition. Any ideas what could be the cause? Thanks in advance

Could be the throttle cable is chaffed. First thing to do is to make sure the throttle arm on the carb is actually fully closed on idle and go from there. You can push it closed with your finger or screwdriver!
