The manual should tell you where to set the needle to begin with, if not start around 3-4 turns out. Prime by opening the throttle to full, putting your finger over the carb and flipping the prop until your finger is "WET". If you can't get your finger over the carb, use a small squirt bottle to put fule in the carb. Close the throttl to idle, connect glow plug igniter, put the prop "BACK" against compression. Then use a chicken stick to flip the prop "Backwards" (opposite of normal direction). Please have someone else hold the plane or strap it down though. If this is a "NEW" engine, an electric starter "may" be needed.
