I have Stihl trimmer that I can’t get running correctly. I bought in America in 2010 and used it for a summer. Then I shipped it to PNG and it was stored for nearly three years (without gas.) I can get it started, but I cannot run it at full throttle. It speeds up as I begin to squeeze the trigger, but then stalls as I get close to full throttle (see the video.) Here are things that haven’t fixed it:
- Adjusting the high speed and low speed screws
- Cleaning the screen on the exhaust exit
- Cleaning the carburetor with carburetor cleaner according to instructions from a youtube video I found
If you can tell me what’s wrong, that would be great. It would be even better if you can tell me how to fix it.
