Hi, I’m looking at a solution to a problem I have with my RV 6 ( O 320) air filter fitting.The problem is that someone has hacked away at the air filter ( K&N E-3260) & filled with silicone as per the photos, I don’t like the look of it at all. The bottom of the Carby plunger & some of the body protrudes below the flat surface on the Carby (see photos)Has anyone seen this before & if so do they have;solution. Thanks
