my 93 force 120 shut down on me when I backed off the throttle. I can only restart motor with a shot of starter fluid in carb, then dies out so i know its a gas problem. Gas is getting to carb because I loosened the bolt on the bowl and gas poured out. I also removed the fuel line from carb and pumped bulb as gas also shot out. Seems the carb itself is not pushing gas in engine. I used to see a little gas come from carbs when I pumped bulb but it doesnt do that now. I tapped carbs to see if needle or float were stuck but that did nothing. Carbs were just rebuilt and it ran fine for a few weeks but now it has this fuel problem.
