The engine barely revs high enough to run smoothly and I need to take it to the dealer right now. If you don't mind pulling the string a half a dozen times or more and then wait on it to warm up so it'll run decent then it's a great trimmer.
I think it does have an adjustable carb , but can only be adjusted with a special tool.
