Can anyone direct me to the drawing and/or instructions for fitting the K&N filter inside the airbox of an updraft carbureted O-360-A1A? I bought a previously flying RV-8 and it seems to me the air filter is not sealing properly between the plate that is attached to the carb in particular, and probably not sealing well against the fiberglass airbox either. The top plate of the airbox has angles riveted around the perimeter to position the filter, but theses angles are installed too far outward such that some of the rubber seal of the K&N 'hides' inside the top plate of the airbox. The rubber seal of the K&N will not contact the plate that is attached to the carb because part of the seal on the filter slides underneath the top plate of the airbox. Seems what I need to do is to install new angles to the top plate of the airbox to insure the entire K&N rubber seal is 'visible' to the plate attached to the carb. Also, how do I ensure a snug seal between the lower K&N rubber seal and the fiberglass portion of the airbox? Some sort of weather stripping? I am hesitant to do this in case it ever came loose and gets sucked into the engine. Hope this was not too confusing..... Thanks
