Sorry for the super late reply. I cleaned the whole thing up and it is straight shaft. I got a new spring for the starter and it still won't recoil back. The guy at Ace said that it need a starter bolt or screw which I don't have. I'll order one of those online and see if that fixes the recoil and hope it has spark. And I agree I don't want to spend lots on this trimmer. My first impression on this trimmer I thought it was a junker but I deicded I'd try and fix it but if this goes into costing a lot then I'm not going to fix it. I've spent around $8.00 on parts such as fuel lines, spark plug and spring. Which makes $18.00 right now.
