I used it in May and now it has no high rpm's but idles fine. This model only has idle adjust, no high/low adjust. The chain lock is not engaged. If I throttle it up slowly it tries to get high rpm's but flutters out back to idle. I put on new filter and fuel lines I had for it and checked the needle and seat assembly and screen in the carb and brake cleaned everything well. New fuel, new plug, same results...no high rpm's...advise here please....Tom

Take the screen out of the muffler and clean, and also clean your air filter.
