i dont think it would have any negative affect. it is very fine mesh it allows air through just fineHow would that effect the amount of intake air being directed over the cylinder fins for cooling?
As long as the filter isnt more clogged causing the grease to suck thru.Grease will stop anything from getting past the filter neck, unlike the turkey necked @dall he keeps slipping into anything to do about a Husqvarna and litter it with little tiny pecker tracks all over the place.
Make a adapter for a v stack in your shop , like a K&N with a pre filter like Outerwear’s , that’s what I did for other saws
