Hi Dan,
I have done the two screwdriver tango to start nuts on quite a few carbs including this one and a few other hard to access things I have worked on. That works great! I have also used the punch to loosen and tighten nuts. My grandpa taught me that one when I was a wee tot. I just had an easier time tilting the recoil back on these motors. I like to have the access and it’s pretty simple to do, just take care not to turn that spring loose. 😮
