Hey Guys. Just fixed one problem and now this other cropped up. I can’t get fuel to the left carb bowl on my CB350. The fuel runs strong through the hose but not a drop in the bowl. I removed the bowl and shot carb cleaner through the bowl intake and it came through the passage fine. I even ran a guitar string into the passage and worked it back and forth to make sure there was no blockage. The culprit then has to be the float valve needle. The orifice is clear and the o-ring is good. The valve pin works in and out like it should. The float moves up and down freely and the tab pushes the pin in when the float is pushed up. The pin retracts when the float goes down. With the bowl back on I can hear the float move up and down when I shake the carb so I know the float isn't sticking. Everything seems to be in order but I don’t know enough about the valve to know what would make it not work. Right side carb works fine. What am I missing? Any help would be greatly appreciated. D.
