I just wanted to comment on the trimmer I purchased about 2 years ago..... I rarely use this product, and have had several issues with it. They seem to be common, because the comments I am seeing here, are all the issues I have had.... 1) Keeping it running at the half choke or no coke setting....2)I have already had to have the pulley system repaired.. and now the plastic thumb bubble is shot, and it looks like I will have to buy a whole new carburetor just for that part... it is not worth it... I will go and buy a different brand trimmer, hopefully with better results... I am, to say the least, disappointed.
