While hovering my Raptor the engine leaned out and died. No restarts. I have dismantled the carb.twice. No debri found. New fuel lines and clunk line. took out tank and pressure tested under water. all OK. If I go full throttle and turn over with starter it will draw some fuel. close to idle and hook up igniter, it will start right up for 2-3 seconds and burn of fuel and die. The fuel lines readfily flow fuel. No obstructions. I do notice the high speed side tube inside the carb. extends inside the low speed adj. side tube looking down the carb. from the top. In fact this same high speed copper tube extends all the way to the opposite side of the carb. barrel opening. I thought they were supposed to meet in the center. Got me baffled. Ron
