Trimmer has not ran for about six years. My father gave up, trying to tune it up. I believe that is all it needs is a good tuneup. It most likely needs a new spark plug also,which you can look it up with the model number of the trimmer. Someone who knows what they’re doing I’m sure will get this running in top-notch again. I had purchased another one in which I don’t have to mix the oil and gas like this one 40:1 ratio model #TB70SS This trimmer is going for around $115 at stores and for only $30 it will not take much money to get it working again.
