I have a 20 year old Sears tiller that has never failed me but the other day the pull cord broke and I need to replace it. The engine is Briggs & Stratton. I have removed 3 bolts and the shield starts to pull off but I can tell there is one more bolt somewhere but I can't seem to find it. Any ideas on where I should look. Here are some pics of what I removed. Thank you.
