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.
This is going to sound ******ed but I promise it works. Empty all the gas out of your trimmer. Fill it with straight WD-40. it will be a pain to start (maybe 10 pulls) but then run the full tank of WD-40 threw it. It will smell like you just lit a BBQ grill but it will clean it completely out. After that tank put your normal fuel back into it and it will run 100 percent better…..promise….
