Ok so I made a tool out of a tire valvl stem and got the trimmer to run right so that makes me very happy. I would still like to purchase the actual tool though for future adjustments. Does the tool have a specific name? All I have found is a "double D" tool. If anyone knows of a website with it please copy and post me the link. Thanks for all your help guys.
I saw a couple about 6 months ago on line , amazon, I believe. Spend if you want, I have found the adjustment very stable so the tool will collect dust.
