Ken Dunn told he you can pick up a screen and deflector for a Husky 272 for under $10. The screen is roughly 3/4" X 1" in size. Whatever you use make sure the screen is stainless steel.
you might check at the local hardware store in the plumbing section. If u look near the area for faucets the screen that goes in the tip of your kitchen sink faucet is stainless steel. Thats what I use and it works great for me.
