    Does the engine bog and quit entirely or is the bog momentary where you can throttle through it and the engine runs OK ? Put a fresh plug in it, get it to bog and them pull the plug. If the plug is dry the problem is likely fuel-flow. If the plug is wet, perhaps there is an ignition problem. The air screw only controls low speed mixture and has almost no effect at W.O.T. Good luck.
