First of all, thanks for the feedback everyone. It is forums like this that help all of us learn. I had an air leak at the carb and back plate. Sealed both. Also backed off the idle. Engine idles great now. I will have to do some fine tuning when weather warms up, but what a difference the turbo conversion makes on this Losi 350. Going to make this 8ight 2.0 a great car to continue to learn on before I make the big investment into a better engine.
