Hello all, my problem may be self inflicted. I have an OLD TB575SS string trimmer. It was running ok, but the recoil spring was not retracting correctly. I took it apart, lubed the coil and it is starting great now. Unfortunately, when I try to gun it, it is a dog. I can grab the head and stop the string rotation. Not sure what I did wrong. Maybe when I removed the clutch. I had to remove the spark plug. Any ideas??
