i have just had the same with a talon hawk,the only way it would keep running was if i kept priming it as it was running.i checked the fuel flow to the carby,completly stripped it,including the jet above the main jet, idling i think, its firm but slides out blew it out both ways every way. checked the float level and the o rings on the inlet, put it back together and it went good.the other thing with mine has not much to do with fuel, but the plastic air vane on the govenor was nearly siezed up and only moving a fraction of what it should. apart from that fuel was the main problem. dont know if thats much help to you at all, cheers micka
