After 9 years with my FX Wildcat I’m due for some maintenance. I’ve shot it straight out of the box with great accuracy with over 2000 squirrels harvested. Recently it has started leaking from the small atmospheric hole in the air cylinder. I ordered replacement o-rings from captain o-rings and watched Earnest’s masterclass videos to replace them. It still leaks out of the hole, so instead of sending it off for repairs I ordered a huma replacement regulator. While I’m waiting on its arrival, I was wondering if anyone has information on if, when or how to clean a Huggett moderator. It has been on the gun from the start and likely needs attention as well, if necessary. I have had no issues with the Wildcat MKI or Huggett until this 9 year mark. The gun has remained deadly accurate. I even carved a custom mahogany stock for it. Thanks for any help
