i just want to move the exhaust outlet so its not blowing on the fuse (pointed directly at fuse), the problem is that it will not move. i took the backnut*** off , tried to move it, nothing, so i tried to loosen the screw in the front of the muffler but it would not turn what so ever.

i put an 10x6 on it and it seemed to spool up fine. im going to test it now.

edit

ok well i just went out and tested the engine. it is an airbleed carb and im still getting used to tuneing it.
i dont know if this is a problem, but it will not run unless the throttle is 1/4 open (are airbleed carbs like that?). it will transition fine and has a lot more power than i was expecting (good thing).
i think i may have a leak somewhere, because if i keep my hand behind the prop i get the "cooling" feel of methanol, and i notice i am getting slime where i wouldnt expect any. although since the muffler is pointing strait at the fuse that may be creating some funky airflow throwing slime all over the plane. i am going to check for leaks anyways
ill run the engine again and cover the muffler w/ a rag and see if i still get that cooling feel, if i do then i know i have a leak.

i also tried to turn the muffler once again, letting it heat up, but that screw still will not turn.

i just remembered, when i pinch the fuel line it dies within a second (the richest setting or the leanest doesnt matter), however on the richest setting the engine will stumble as it goes to WOT.
