Got a new tiller. 4 questions. Notice the 1/8 inch gaps around the sides. Do I need to address this ? (Spacers?) notice the gap on the back. Should I round off the butt of the tiller to get it snug ? 3rd question should I mount flush on top, center or flush on bottom? The old one was centered. Last question..when I drill the holes in the new tiller do I need to seal them before assembly? Thanks
