it does matter. keep grass clippings in there. but don't forget to change them regularly. scientific studies have been done proving that engines perform better when supplied with freshly cut lawn scented air.
it's just a hole, it will be fine. leave it open, weld it shut, pee in it. either way it won't hurt or benefit anything.
