How Break -In Saito 65 engine?
Run it a little rich for a few tanks. (Have the high speed needle out a ways from where the motor would run a smooth peaked out high speed.) You always want to see a smoke trail behind it. Don't run it wide open continuously until after three or four tanks. After the first tank. Start trying to figure out where your needles are at. Start trying to set them.
Enjoy,
