Hello Sir,
The motor gets plenty of cooling in the plane. The needle setting is not very clear in the manual(or we just dont understand what they mean. All the guys I fly with are DA or DL guy, not that theirs anything wrong with that, but the settings in their motors are a little different.
Dont understand what you mean by(fuel used), unless you mean what grade,(93 octane, 90 to 1 syn.
The muffler is the rap around Evolution.
The prop was a 24x8 but I wipe it out on a land so now I have a 22x10. both props made the motor run the same.
2 yrs ago I had a bad crash I look the motor over real good, but.
I guy told me today that I might have a crack in the carb throat or maybe the reeds are crack, is this possible.
