ok, i have spark. i know its not getting fuel cause when i add gas to the cylinder it fires right up and runs till there aint anymore gas in cylinder. i took carbs off to clean them so i figured the float bowles were just empty but i pulled and pulled alternating between kill switch on and off for over an hour and a half and no go. im pretty sure everything is hooked up right. the only thing that i might have messed up is the way the fuel line is run?? does it come up from underneth the carbs or more from around and down to the T? or any other ideas before i pull them off and start looking for something else???
