Hi!
Have you tried setting the engine rich? I mean opening the high speed needle when the engine rews at full trottle so the the rpm drows due to too much fuel?!
Forget about removing the carb,just check so that the carbs is securely mounted.
Never ever try to set any screws when the silencer/engine is hot!!! Screws should always be tightened when everything is cold.They will loosen otherwise!
A gasket between the engine and silencer isn't necessary!
Run 5-10% nitro fuel and an OS 8 or ENYA 3 or 4 plug.
I actually tried this last night. I turned the high-speed needle counterclockwise a good two rotations and started it up. I could tell it was very rich as it was bogged right down, sputtering, and billowing smoke. The sad part is after doing that, i brought it back to its original position and it ran like a bear. WTH.
Ugh, now i'm just afraid to fly it because im worried it'll start acting up again mid-flight.
