RE: Evolution PTS at Altitude - Issues, Please Help!
Because of your altitude in Boulder, I would remove the "set ring" and re-adjust the needle until it runs well at altitude.

You will make things a lot easier if you put an A3 plug in it. You have a great engine there that puts out a lot of power for the price. I wouldn't take 5 OS's for mine. You just need to get things right. The high speed was lean in the video. The low end sounded wet. See what the proper heat range plug gives you. The A3 is a game changer in the .455.
The muffler gasket will have no effect. You can run it without them if you want. With the OS 8 plug, try easing the throttle up and down in increments so it has time to get rid of excess, unburned fuel. |

Just as a side note, i've always had to slowly ease the throttle to high. If i did it quickly, it would stall the engine and it would hesitate.... a lot. I'll see if i can get one of those plugs and see what happens. I'll also try riching the crap out of it (turn counterclockwise until smoke starts to billow)
Thanks! |

Yes, tighten when the engine is hot. But it is more important to tighten after the engine has cooled off again. I have had more trouble with engines with exhaust gaskets, unless you consider RTV a gasket.</p> |

Hi!
Have you tried setting the engine rich? I mean opening the high speed needle when the engine rews at full throttle so the the rpm drops 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. |

Ugh, now i'm just afraid to fly it because im worried it'll start acting up again mid-flight. |

Jaka, I have a new in the box Evolution .46NT downstairs in my shop right now. I would really like to give that to you one day and watch you chase your tail trying to get it to run any differently than the OP's engine is running right now.

RE: Evolution PTS at Altitude - Issues, Please Help!
I'm going to invest in a RPM meter. Does anyone know what a good range would be for the low speed and high speed? I think it will help me keep it tuned to the changing conditions better.
Thanks! |
