Had the DC out hooking to disc, running for 10-15 mins, then up and died at idle as if you turned it off, went over hit the button fired up immediately died, check fuel to carb, good, bowl was full, drained bowl and could blow through fuel line, needle was out of seat, ck spark, seemed good, shocked the $&@! Outa me, good arc on tester, removed and cleaned plugs, re cranked, plugs dry, left plug out while cranking, saw valves still moving, as all this cranking is going on carb is pouring fuel from inlet. Some sort of zenith carb, anyone know model , also how can carb shoot craps at idle with no stumble etc..any help would be great thanks Dustyah
