Initial needle settings for OS .32 SX?
Start with 1 1/2 on the main, 2 1/2 is way to rich. You'll end up with the mixture screw too lean to compensate if you start there. Leave the mixture screw where it was set at the factory. If you have changed it I have had good luck with setting mine at 2 1/2 to 3 turns out to start. Be sure the throttle is fully closed when closing the mixture screw before adjusting it.
