hey guys i was wondering if any of you could help me out with my hedge trimmer. first of all its the Stihl hs 45. ive only had it for maybe three years with little use. I took it out the other day and it had problems running at full speed. It seemed like there wasn't enough fuel coming in so it would just die if i kept it running a full speed. Running at half speed it did great, no problems what so ever. Im thinking its a carb. issue. ive only used it maybe 15 times though. Do you see anything else that could cause this problem.
