First, with the glow driver removed, open the throttle, put your finger over the carb, and flip it a few times until your finger is wet. Now go to 1 or 2 clicks above full low throttle, add the glow driver, and flip it the right way (I like to keep my prop so you feel the compression at about 1 O'Clock). If, the engine starts, great, but if it kicks back too hard, or if it kicks and runs backward, then re-prime, and try a backward flip (but when flipping backward, be sure to let the stick slide off the end of the prop because once it catches, it's coming back in the direction of the stick!).
