Filter fixes for hard to find remington filters. Be sure to keep a edge tag on because that is how the filter is attached to the screen. Looka like an almost exact fit for pl4/pl5 and maybe others. Also good for 660/754. Put between carb and filter adapter for extra protection when you don't have the correct filter. Not sure if it helps anyone. But it's something to consider. Make sure screen is on carb side so the filter or any filter material doesn't get sucked into carb or saw. Let me know what you guys think. Thanks!
