50hp Johnson carb trouble

[Slife2]

I have a 50hp Johnson and every time its under a load the bottom carb shoots alot of fuel out and the top carb acts like it aint doing nothing. I put new fuel line on and cleaned the carbs. It still runs like crap under a load. If anyone knows what I can check for now I would appreciate it. Thanks

Re: 50hp Johnson carb trouble

Check the high speed circuit in the top carb for debris or a stuck (closed) needle on the float chamber.....did you rebuild those carbs with new kits and reset float levels when you cleaned them? How well does it start and idle?
