Ryan, I just had a 120 muffler to loan him and he let me fly it) had a
set-up here with the tank mid-way back, Perry and Macs and when we went to
muffler and tank forward everything worked. I know Jerry's set-ups have
worked on other motors so I see no reason it wouldn't work on the 120. I forgot
what angle the motor was mounted, but I know someone here has that answer

<P>Jason,</P>
<P> </P>
<P>The reason I ask, I have the 120AX in a Venus II and with the stock
muffler I have a fuel draw problem. The tank is all the way against the
back of the firewall. If I adjust the mixture for max rpm with the nose
pointed up, it is blubbering rich in level flight. I was going to
experiment with adding more restriction at the exhaust outlet, but just
stuck it on the rack and have not touched it.</P>

<P>A couple of guys have that engine with the Jerry Smith style mousse
can mufflers, and they work great. They have much more back pressure but
turn up more rpms. The extra muffler pressure helps with the fuel
draw.</P>
