I lost the back half of the muffler on my Magnum 1.20 a couple years back. The
engine was so loud it caused pain in the ears. I fly out in the desert where there
is no noise restriction what-so-ever....I had to put the plane away and fly something
else....I didn't have any hearing protection, and trying to tune the engine was too hard
on the ears. Of course when the muffler lost the back half it threw the tuning of the
engine off because of the loss of fuel tank pressure and the back prssure to the engine
it had with the muffler in proper operating shape.
FBD.
