It met it's demise as part of my conversation to the church of safety wire and other positive retention. http://www.sonexb...
I flew today, after my latest adjustment and it seems pretty good. One odd thing though.

If I enrichen t...

I did add some sealing to the air filter shroud. flap closed.png This is installed so the flap will open and prevent high pressure, or if a bird flies into the intake and blocks the scat tube then it w...
