Howdy folks, I've been looking for a description or write-up on the mods you can do to a J cowl to keep it from lifting up in flight. I've searched the forums here and the internet and haven't been able to find it, but I know I've seen it somewhere.. Can anybody point me in the right direction? My A&P went through a lot of effort shimming my newly overhauled engine so that it's all properly aligned, but the cowl lifts every time I fly and then things are slightly out of whack again,
