Default RE: TT .91F Pre-Ignition "Girgling sound while flying"

I am running the choke adapter now when getting this sound but there was a period I was breaking in the engine I didn't use the choke and it ran perfectly no noise or nothing. I put the engine on a .60 size H9 Uglystick to break it in. Sticks are perfect for breaking in engines as the engine runs in the open air with no cowel. Now it's in a World Model .60 Zero. Could the fiberglass fuseloge be making a resinating sound.
