The only ones I have ever installed were the short straps where you bend up the "ears" against the head of the rod bolt (Briggs part # 220756). I just purchased a rod for an old 1970s 3 Hp flathead I am restoring and it comes with 2 (thin) washers instead of the locking strap. It looks like they are Briggs part # 222282 if purchased separately. The instructions with the rod state to use these instead of the locking strap. Can someone tell me how these (typical/normal-appearing) flat washers can serve as a lock washer to keep the rod bolt from loosening?
