Ive been running my new fs85 for about 2 weeks now and it seems to be rather tempermental. First is getting it started. It wont start without at least 4-5 pulls. Then when i edge with it(gas cap side down), if it is under half tank of gas, it will loose power intermitantly and bog down considerably until i turn it back to trimming position. What can i do to make it run ideally? Im ready to turn it into a extended reach hedger and get something else.
